Introduction

What are autoclaved matrix engineered

mineral boards?

Promat manufactures a number of autoclaved matrix engineered

mineral boards, including PROMATECT®-H and PROMATECT®-L500.

The autoclave process exposes the mixture of raw materials to

elevated temperatures and pressures to create a product with

useful, versatile and beneficial properties:

• Non-combustibility

• Good impact and abrasion resistance

• Moisture tolerance

• Good dimensional stability

• Stability in fire conditions

• Good insulation properties when exposed to fire

The fire insulation properties of Promat’s matrix engineered mineral

boards are mainly due to the presence of a controlled moisture

content held within the board.

PROMATECT®-H is a laminated cementitious board which is

subjected to heat and pressure in an autoclave to form a sturdy,

multi-purpose matrix engineered mineral board.

PROMATECT®-L500 is a monolithic matrix engineered mineral

board formed by pressing together autoclaved calcium silicate

spheres called PROMAXON®.

PROMATECT® 100, in fact, is a hybrid development of matrix

engineered mineral and gypsum technology using PROMAXON®,

providing the following performance enhancements:

• Superior insulation properties when exposed to fire

• Excellent workability - easy to cut

• Smooth and flat surface

• High flexural strength providing the ability to form curved linings

• Cost efficient

Improved fire insulation

The composition of the new PROMATECT® 100 board contains a

key component which improves the fire insulation of the product,

thanks to an endothermic process which produces a chemical

change accompanied by the absorption of heat.

The critically important component is autoclaved matrix engineered

mineral spheres (also known as PROMAXON®) bound in a mineral

matrix. It is PROMAXON® in combination with the mineral matrix

that eventually creates the endothermic process when exposed

to fire.

The end result is significantly better fire insulation than that

provided by either traditional matrix engineered mineral boards or

gypsum boards. The new PROMATECT® 100 boards have both a

small amount of free water in the PROMAXON® and chemically-

bound water in the mineral matrix. By producing more water and

retaining it longer within the board, fire insulation is improved.

What exactly is PROMAXON® and how

does it contribute to board performance?

PROMAXON® is a synthetic hydrated matrix engineered mineral in

spherical form. The outer shell of close-knit micropores forms the

linking network for the mineral matrix of the PROMATECT® 100

board. This is a key factor in the board’s cohesion and stability in

fire conditions. A mineral additive acts as filler in the gaps between

the spherical PROMAXON® particles.

In fire, the release of free water within the board, and then the

chemically-bound water from the mineral matrix, cause a cooling

effect which reduces the temperature rise on the non-fire side of the

board. However, before the water can escape from the board, the

PROMAXON® spheres recapture part of the water that has been

released. This then creates a further endothermic process that

gradually releases the recaptured water molecules, thus creating a

further drop in the rate of temperature rise.

In the application of PROMAXON® technology and the development

of PROMATECT® 100, Promat have created a new generation

of boards which combine the advantages of traditionally

manufactured matrix engineered mineral and gypsum boards with

other outstanding advantages.

Promat

Environmental

Health & Safety

(EHS) Policy And

Other Related

Developments

Promat International Asia Pacific is one of the main subsidiaries of

Belgium’s Etex Group of companies. Headquartered in Brussels,

Etex consists of some 135 business units across 40 countries,

employing more than 12,500 people worldwide.

As ecologically sustainable issues become increasingly important

and the cause of mounting concern in a rapidly globalising

world, Etex has consistently articulated a well-defined

environmental, health and safety policy as a benchmark for all

its member companies.

Be Green And Protect The Built Environment?

Despite being surrounded by the steel, concrete and glass of

crowded urbanity, Promat realises that Mother Nature will always

hold the key to how we humans live. Coming from cities and

personal, climate-controlled spaces, we frequently tend to

overlook this simple, undeniable fact of life…a fact reconfirmed

time and again.

It has become obvious, to Promat at least, that we have no choice

but to do much, much more for our environment, both directly and

indirectly. Recycling plastic bags and using less fossil fuels for

example, is good but no longer enough. We are inclined to agree

with those who believe that the best chance for society and a

sustainable future is to follow the master plan – plain for all to see

in nature – and actually design a very high level of true recyclability

into everything we do, especially in the structures and built

environment we live and work in. Clearly, a fundamental and broad-

based change of mindset is first essential. In the meantime we have

to start somewhere.

It is noteworthy that Etex Group policies are based on a sound

value system of corporate social responsibility. The Group’s very

own Environment, Health and Safety department is dedicated solely

to environmental, health and safety issues of our factories and

offices, our people and the communities in which we work. In Asia

Pacific, environmental awareness varies, reflecting the different

stages of development and maturity present in the region.

Environmental issues are definitely on the agenda and destined to

generate more significance in the near future.

Our support, adherence to and respect for environmental issues is

highlighted through our membership of the Green Building Council

of Australia. This not-for-profit initiative aims to promote the

transition of building design, construction and operation to

optimum green principles. The same green principles are core

Promat corporate beliefs.

In other Asia Pacific states, plans are well underway to ensure

that all future buildings will address and resolve numerous

environmental concerns. It is good for the building and the

occupants of the building. It is good for the local community and it

is good for the environment. A true win-win situation that can

only get better, improving the quality of life for our children and our

grandchildren and their children.

Environment Management Systems are tools for managing

the impact of an organisation’s activities on the environment.

Certified to the international standard ISO14001, Promat aims

to consolidate environmental gains through the implementation of

effective environmental management. Adherence to this standard

ensures environmental issues are considered within decision

making practices.

We must remain alert and mindful that the future will demand much

more of environmental issues. There will certainly be some daunting

challenges and we will need to continue adapting, as we have done

in the past. Our new production lines in our factories across the

world are a reassuring case in point…there’s very little waste and

we save a lot of energy. We can be environmentally responsible

AND make good business, particularly if we use wisely the

accumulated experience and considerable resources available to

us.

Making the world a better place in which to live and work – for

ourselves and for society as a whole – is always a matter of policy

priority for Promat and the Etex Group of companies as a whole, for

now and for the future.

Committed To Environmental Concerns

As a global leader in the business of the proactive fire protection,

Promat fittingly also takes a proactive approach to environmental,

health and safety issues. Starting in 2005, Promat implemented its

own Environment, Health & Safety policy, entitled “Promat –

Towards Sustainable Growth”.

Promat is therefore committed to:

• the creation of a safe working environment for all its employees

and the societies in which the company works,

• control and minimise potential negative impact

on the environment,

• include EHS concerns in the development of its products

and systems,

• continuous improvement of its EHS performance,

• transparency and open dialogue based on facts and figures

with all its stakeholders,

• the principle that EHS Due Diligence shall be used as

standard practice for Mergers and Acquisitions,

Investments and Divestments.

The policy applies to all Promat entities and necessary resources are

allocated in order to enable correct implementation of its EHS policy.

Before making critical investment or acquisition decisions, the

environmental, health and safety aspect is systematically evaluated.

Accordingly, Promat has developed a checklist which enables the

company to form an accurate overview of the relevant EHS aspects

in a relatively short space of time.

Group Environmental Policies Continually Evolve

It should always be noted, however, that – to be both meaningful

and accurate – realistic environmental policies must continually

evolve. After all, the world around us is constantly changing. A good

reflection of this point of view are the recent additions to the Etex

Group’s EHS policy.

These take a broad view of pertinent ecological issues, along a

time line between 2007 and 2011, while looking at specific

considerations, such as:

• OHSAS certification

• Environmental reporting

• Accident analysis

OHSAS Certification

The Etex Group and Promat are rightly concerned with all matters

related to ISO14001 certification, the universally recognised

certification process for most environmental management concerns.

Now, however, the group insists that all group factories will have to

comply with OHSAS certification. Implementation is expected to

start in 2008 and be completed before 2010.

Although not an international standard, OHSAS Certification –

based on the Occupational Health & Safety Assessment Series –

gains increasing recognition around the world. It is formulated

and implemented on a framework of corporate occupational

health and safety policies, planning, implementation and

operations, checking and corrective action, management reviews

and continual improvement.

Introduction

Fire Safety In The Building Industry

Like buildings, fire control is a continually evolving science that

generally starts with the idea that a bucket of water or sand in the

right hands at the right time and place can make the difference

between a minor incident and a major disaster. Unfortunately, we

live in a built environment that is considerably more complicated.

The risk of a fire depends on a building’s use, location, size,

occupants, design and construction. In general, the larger the

building, the greater the risk to life and property.

A vital factor in reducing risk is to provide physical barriers to

the spread of fire within the building. This is done by dividing the

building into a series of compartments contained within fire

resisting walls and floors. This fundamentally effective concept is

generally referred to as “compartmentation”. Each compartment,

regardless of penetrations, is fire-proofed to an optimum level to

prevent the spread of fire, smoke and toxic gases.

The protection of the structural frame, the enclosure and protection

of vertical and horizontal openings, effective fire-stopping at

junctions, protection of service penetrations, use of low flame

spread finishing materials and non-combustible materials are all

important considerations.

In addition, the fire performance of external walls and roofs and

their proximity to other buildings are essential factors to consider in

the prevention of spread of fire between buildings.

All these measures are referred to as “proactive” fire protection for

they are systems that do not require power or water to operate in the

event of a fire. They protect on demand, as and when necessary.

“Active” fire protection measures are those that use an integrated

system consisting of sprinklers and alarms that require electricity

and water to realise their full potential in fire situations.

Two other fire design concepts also have significant bearing not

only on fire safety but also architectural and engineering expression.

These are building design according to (1) Prescriptive Building

Codes or (2) Performance-based Building Codes.

Prescriptive Building Codes,

The Orthodox View To Building Fire Safety

Traditionally, most design for fire has been based on prescriptive

building codes by which fire safety is usually achieved by designing

various components in isolation. The building layout must usually

meet certain requirements, such as maximum compartment size

and minimum/maximum dimensions of the exit routes. The building

fabric, structural elements and other building components only

have to meet prescriptive requirements. Any possible interaction

between different fire protection measures is not considered, unless

explicitly allowed as an acceptable trade-off.

Prescriptive approaches in fire design often create problems for

modern buildings with mixed use occupancies, large assembly

areas or unique atrium designs. This is because in the world of

modern building design and construction, a variety of security and

life safety questions are asked of engineers and architects who

must then provide a functional building in which solutions ideally

balance design with the risks associated with any building-

regardless of size and occupancy.

Conversely, compartmentation as described by prescriptive codes

can result in dividing the building into small cubes that limit

architectural expression and effective functioning of the structure.

Furthermore, current building design practice does not consider fire

as a design condition. Instead, structural fire endurance ratings are

prescribed in building codes using standard tests on individual

components and generally do not represent real fire hazards in

modern buildings. Prescriptive approaches also do not consider

the fire performance of structural connections or the structural

system as a whole or the multiple performance demands on fire

proofing materials.

Building codes across the world today are undergoing a major

evolution to address their ability in providing flexibility in the building

and architectural design process and use of a building together with

cost-effective fire and life safety measures.

Performance-based Fire Design,

The Way Of The Future

Undoubtedly, prescriptive local fire and construction codes ensure

that modern buildings are designed to minimise the likelihood of a

major fire. On the other hand however, increasing levels of public

expectation and rising standards of public health protection, hand

in hand with larger and more complex building types, it is clear that

the old, “rule of thumb” prescriptive applications of fire safety

design are not only inflexible but can be considered inadequate and

out of date in the field of modern fire engineering.

The practical fire engineering approach is to examine and think

through problems associated with aspects of fire safety and

protection in modern buildings – in this case, fire resistance

performance – and to base solutions on a solid foundation of

reason, common sense, science, mainstream engineering,

practicality and cost-effectiveness principles.

At this point in time, performance-based fire engineering design

demonstrates clear signs of increasingly coming into its own around

the globe. In fact, the use of performance-based design creates a

level of fire safety equal to or better than the prescriptive code while

providing the local authority with a recognised engineered basis

that accepts the performance-based approach.

Performance-based design provides the opportunity to overcome

the differences between codes of various countries, allows

designers to create engineered solutions and generally results in

cost effective global fire safety.

Fire safety is one of the components of building safety. Most

countries have developed elaborate legislation regarding fire-safe

construction. One of the important tasks for Promat is to maintain

its knowledge and understanding of the specific rules in each

country and help close the gap between regulations and real life.

This is done by providing a free advice service and assisting parties

within the building industry to make the right choice to realise true

safety. Promat technical staff are engaged in a constant search for

solutions. They are experts at fire safety legislation, follow the

changes in regulations and continually test new, practical solutions.

Support in materials, research and fire tests is given by Promat

Research and Technology Centre (PRTC), based at corporate

headquarters in Belgium.

Research & Development

Fire rated constructions are seldom put to the test because not

every building burns down. The purpose of fire rated constructions

is to allow people to escape from the hazard and reach safety. We

test our products constantly in order to establish and refine the

performance of Promat systems.

Promat run continual investigation programmes at the PRTC

facilities in Belgium. The PRTC testing laboratories are accredited

to EN45001. The PRTC furnaces are state-of-the-art and offer

multiple possibilities for the testing of construction systems

under development.

All Promat materials are manufactured in accordance with

accredited EN ISO9001: 2000 and ISO14001 quality management

systems. Comprehensive testing of all Promat products and

systems has been carried out by independent and nationally

approved laboratories around the world in order to meet the

relevant sections of BS476, AS1530, EN and ISO etc, as well as

many other international test standards.

What Is Proactive Fire Protection?

PROACTIVE FIRE PROTECTION products and systems are tested

by independently approved testing authorities under standard test

conditions. The fire performance standard and terms most relevant

to the materials and elements of construction described in this

handbook are as follows.

Fire Testing Methods: Fire Curves

The fire performance of any system will vary depending on the

heating conditions it is exposed to. Different national and

international fire curves have been developed to simulate fires

carried out in fire test furnaces, by recognised national

organisations. These include:

1. The Standard Cellulosic

Time-Temperature Curve

This ISO-based curve is used in standards throughout the world,

including BS476, AS1530, DIN4102, ASTM, and the new European

Norm (EN). It is a model of a ventilation controlled natural fire, i.e.,

fire in a normal building. The temperature increase after 30 minutes

is 842°C.

2. The Hydrocarbon Curve

This curve is a simulation of a ventilated oil fire with a temperature

increase to 1110°C after 30 minutes. The Hydrocarbon Curve is

applicable where petroleum fires might occur in an open

enviroment, i.e. petrol or oil tanks, certain chemical types etc. In

fact, although the Hydrocarbon Curve is based on a standardised

type fire, there are numerous types of fire associated with

petrochemical fuels which have wide variations in the duration of

the fire, ranging from seconds to days.

3. The RABT Curve

This curve was developed in Germany as a result of a series of test

programmes (e.g. the Eureka project) into the effects of fire within

enclosed spaces such as road and rail tunnels. In these situations,

the inability of the heat to dissipate in to the atmosphere, and the

flue like effect of the tunnel geometry feeding air to a fire (similar to

a blacksmiths bellows) results in much faster fire growth and higher

temperatures. In the RABT Curve, the temperature rise is very rapid,

up to 1200°C within 5 minutes. The duration of the 1200°C

exposure is for either 30 or 60 minutes, depending on type of

tunnel, e.g. road or rail. The temperature then begins to drop as this

curve has a defined “cooling off” period of 110 minutes.

4. The RWS Curve (Rijkswaterstaat)

This model of a petroleum-based blaze is based on a 300MW

load fire occurring within an enclosed area such as a tunnel.

Developed in the Netherlands specifically for use in tunnels, it is

internationally accepted. For instance, the 2007 edition of NFPA

502 will require tunnel structures to be protected to the RWS level

of exposure. The temperature increase after 30 minutes is 1300°C

with a peak of 1350°C.

5. The External Fire Exposure Curve

This model is for fire exposure external to a building and open

to the atmosphere, where there are additional possibilities for

heat dissipation resulting in lower fire temperatures. There is

a consequential lower level of heat exposure. Temperature

increase is approximately 680°C after 20 minutes and remains

constant throughout.

6. The Slow Heating Curve

This curve simulates a slow growing fire. It is basically a

combination of two curves, one for the first 21 minutes representing

the smouldering effect of materials and one for subsequent periods

representing the growth of the fire towards flashover.

7. Furnace Pressure

As well as controlling the exposure temperature, the test standards

require that the air pressure within the test furnace is maintained at

a positive level in an attempt to create a worse case scenario and

force hot gases and flame though the specimen under test. In

addition, thermocouples are fixed to the unexposed face of the

specimen to measure the performance of the system against the

transfer of heat from the hot to the cold face of the specimen.

Fire Test Standards:

Reaction To Fire & Tests On Materials

AS1530: Part 1:1994

Non-combustibility test for materials.

This test classifies materials as either ‘non-combustible’ or

‘combustible’. It is the most stringent standard for the fire

performance of materials and gives a measure of the heat and

flames generated by the material under standard heating

conditions. Non-combustible materials can be used without

restriction anywhere in a building. Their use ensures that hazards

due to smoke and toxic gases are minimised and that the fabric of

a building will make no contribution to a fire. All Promat board

products are non-combustible.

AS1530: Part 3: 1999

Simultaneous determination of ignitability, flame propagation,

heat release and smoke release.

This test sets out methods for the assessment of building materials

and components according to their tendencies to ignite, their

tendencies to propagate flame, the heat release once ignition has

occurred and their tendencies to release smoke.

AS 3837: 1998

Method of test for heat and smoke release rates for materials

and products using an oxygen consumption calorimeter

This method of performance measurement uses a cone

calorimeter used to measure HRR (heat release rate) time to

ignition and smoke production.

Class 0 (As defined in relevant building regulations)

a) Composed throughout of materials of limited combustibility, or

b) Class 1 (to BS476: Part 7: 1987) material which has a fire

propagation index (I) of not more than 12 and a sub-index (i1) of

not more than 6.

It should be noted that there is no test standard which can provide

a report confirming that a product has a Class O status. The test

reports for non combustibility (BS476: Part 4) or Surface spread of

flame (BS476: Part 7) and fire propagation (BS476: Part 6) must be

used to ascertain the classification status of any particular product.

Fire Test Standards: Fire Resistance

& Tests On Complete Systems

AS1530: Part 4: 2005

Methods for fire tests on building materials, components

and structures

This standard provides methods for determining the fire resistance

of ceiling systems, partitions, doorsets, shutter assemblies, damper

assemblies and air ducts. It should be noted that the Building Code

of Australia (BCA) continues to recognise systems and products

tested to earlier versions of AS1530: Part 4, e.g. the 1997 version.

AS4072: Part 1: 2005

Components for the protection of openings

in fire-resistant separating elements

This standard sets out requirements for determining the fire

resistance of penetrations through separating building elements, as

well as control joints between building elements.

Assessments/Appraisals

Test reports only relate to what has been tested and allow no

variations. Changes to a construction tested under the British,

Australian or European standards will require either another fire test

or an assessment.

An assessment is a desktop study undertaken by an experienced

fire consultant that allows variations from a tested design. The

nature and scope of any variations will largely depend on the size

and configuration of the test specimen.

Project specific assessments can also be produced, tailored to the

specific needs of a building project.

Performance: Explanation Of The

Failure Criteria Used In Fire Testing

Unlike the previous tests and terms discussed, fire resistance is

not a property of an individual material but a measure of the

performance of a complete system of construction when exposed

to the standard heating conditions described above.

Loadbearing Capacity

The ability of a specimen of a loadbearing element to support its

test load, where appropriate, without exceeding specified criteria

with respect to either the extent or rate of deformation. (Please note

that within AS1530: Part 4, the term “Structural Adequacy”

describes loadbearing capacity).

Stability

The ability of a system, e.g. ventilation and smoke extraction

ductwork, to remain in place and capable of fulfilling its intended

function throughout the duration of exposure to fire. (Please note

that within AS1530: Part 4, the term “Structural Adequacy”

describes stability).

Integrity

The ability of a specimen of a separating element to contain a fire

to specified criteria for collapse, freedom from holes, cracks and

fissures and sustained flaming on the unexposed face.

Insulation

The ability of a specimen of a separating element to restrict the

temperature rise of the exposed face to below specified levels (140°

mean rise, 180° maximum rise).

Fabrication of Board Systems

Fastening & Fixing

The type of fixings used when installing PROMATECT® 100 board

are important as they determine the support of joints and stability of

a structure. In general, a fixing should meet the following

rules/requirements.

1) Corrosion resistant.

2) Stainless steel or galvanised nails are recommended for timber

framing. Do not use screws when the board forms part of the

structural bracing.

3) Stainless steel, zinc or other plated self-drilling screws are

recommended for steel framing.

4) Fixing points should be located at least 12mm (preferably 15mm)

from the sheet edge and 50mm and 100mm from sheet corners.

The nominal centres of fixing are generally recommended at

200mm and 300mm throughout this handbook.

1. Nailing

The most economical method of fastening is to use pneumatic

nailing and stapling equipment. For best results using screws,

variable speed cordless screwdrivers with torque control have

proven the most successful.

When fixing PROMATECT® 100 board using nails, the following

should be noted clearly.

• Do not over-drive the fixings, as this may reduce the holding

capacity of the fixing to the board.

• Fixings should be drive straight into the board and at best

embedded 0.5mm below the board surface.

• Do not damage the board around the fixing or its edges. Cracked

sheets should be replaced.

Nails can be driven directly through PROMATECT® 100 board into

timber framing, without pre-drilling, provided they are at least 12mm

from the edge of the board and the back face of the board is fully

supported while drilling.

In areas of high humidity, galvanised nails should be used. Panel

pins, oval or bullet head nails should not be used. Nails should be

located 50mm and 100mm from corners.

Fixing guide as below, used in conjunction with drawing above:

2. Screw Fixing

When fixing Promat board, especially to steel frames using screws,

the following should be noted.

• When fixing into steel framing with a thickness greater than 1mm

drill point screws should be used.

• Use a high-torque variable-speed screw gun with a maximum

speed of 2500 rpm fitted with a depth gauge.

• Do not over-drive, as this may reduce the holding capacity of the

screw. Reduce drill speed as the screw pulls the board against

the framing.

Note should be taken that when fixing to steel framing, always fix to

the open side of the flange first to maintain a flush outside face.

Drawings below illustrate the correct sequence of installation.

Incorrect sequence of fixing to steel stud

Correct sequence of fixing to steel stud

Use self-drilling or self-tapping screws when securing boards

to steel. For all other situations, drywall screws (e.g. Hilo) are

generally suitable.

Boards in thicknesses greater than 15mm can be edge screwed.

Self-drilling or self-tapping screws are suitable. If edge screwing the

board, minimum screw penetration should be 25mm or twice the

board thickness, whichever is greater. If screws do not have a deep

thread, pilot holes should be drilled and care should be taken not to

overtighten. Screws should be 50mm from one corner and 100mm

from the other.

3. Staple Fixing

Boards may be stapled to timber supports using an industrial

staple gun. Staples may also be used for edge to edge fixing of

boards greater than 15mm thickness. Staples may be used when

fire resistance is required but Promat should be consulted for

further details.

Fastening & Fixing


Forming Holes

Very often apertures need to be cut within a board in order to allow

for penetration of services such as switchboxes, lights, access

panels etc. Therefore, the following procedures would serve as

general guidelines to achieve this requirement.

i) For smooth, clean cut circular holes:

• Mark the centre of the hole on the board,

• Pre-drill a hole to be used as a guide,

• Cut the hole to the require diameter using a hole saw fitted to

a heavy duty electric drill where the central bit is inserted into

the pre-drilled hole.

ii) For small irregular holes:

• Small rectangular apertures can be achieved by forming a

series of small holes (using a drill) around the perimeter of

the opening,

• Tap out the waste piece from the panel face carefully. Make

sure that the edges are properly supported in order to avoid

damage to boards,

• Rough edges can be cleaned up with a rasp or grade 40 grit

glass paper.

Nailing and hammering for openings

iii) For large openings or apertures:

• Score deeply around the perimeter of the opening using a

sharp tool,

• Form a large round hole in the centre using the method

previously described,

• Saw cut from the centre towards the corners of the opening,

• Tap waste pieces from the face side and if necessary clean

rough edges with a rasp or with at least grade 40 grit sand

paper. Radius corners with a half round rasp to eliminate any

stress points.

Apertures

Alternatively, for neater openings:

• Predrill a hole of at least 10mm diameter at the four corners of the

openings. Mark lines between hole to hole (forming a rectangular

shape) as guide and cut along the lines using jigsaw or hand saw.

• Cleaning the rough edges of the hole can be done by using

a rasp.

Apertures opening using alternate method

NOTE: Never make holes by using heavy hammers, cold chisels or any other

“aggressive” methods. This will damage the underside of the boards and

adversely effect the fire performance of the system.

Loading & handling

Promat boards are supplied on pallets suitable for fork lift

unloading. If crane off-loading by slings is envisaged, care should

be taken to avoid damaging edges of boards. All pallets and crates

can be safely handled by using a fork lift or hoisting equipment and

straps. Steel cables should not be used as they will damage both

the pallet and the boards. Where the crates have to be removed

from a box container, care should be taken not to subject the crates

or pallets to any impact shock, as this could possibly result in

cracking of the boards.

Always drive the delivery vehicle as close as possible to where the

boards are to be used. When transporting the boards it is essential

to firmly secure the pallets to prevent sliding. If the boards are

subsequently moved around the site, the boards should be placed

on a rigid base suitable for lifting by the forklift tines. Promat boards

should always be stored on a rigid base.

10


Loading & handling

Storage

Promat boards are supplied with protective plastic sheet wrapped

around the timber crates. This protection should not be removed

until the boards are ready for use.

In general, the following steps should be taken to ensure that the

boards remain in good condition during storage.

a) Promat boards should be stored on a covered and dry, level

ground, away from the working area or mechanical plant.

Stacking of Promat boards

b) Pallets should be a maximum of 800mm high, on firm level

ground. If two or more pallets are stacked, the total stack height

must be less than 3200mm.

Maximum height of stacking

c) The boards must be protected from inclement weather.

Protection of Promat boards

d) The boards must be stored under cover.

Storage of Promat boards

Handling

The following recommendations must always be taken into account

when handling the panels.

i) Wherever possible, always lift boards from the stack below

rather than slide board on board. This will prevent damage or

scratches occuring to the lower boards.

Lifting of Promat boards

ii) Always carry the boards on edge but do not store on edge.

Ensure edges do not get damaged when handling sheets.

Carrying Promat boards

Cutting

PROMATECT® 100 boards can be worked with conventional

woodworking equipment although the use of hand saws with

hardened teeth is recommended (see pages 11 and 12 for details).

Boards greater than 8mm in thickness may be more easily cut using

a power circular saw in conjunction with tungsten carbide tipped

blades or a jigsaw. For rough cutting, 8mm sheets can be deeply

scribed and broken over a straight edge.

Promat recommend that all cutting should be carried out in well

ventilated spaces, using dust extraction. Operators should wear

protective face masks at all times.

There are a wide variety of applications and fixing methods possible

with Promat boards The method to be used is dependent on a

number of factors, amongst which include:

1) The shape of boards, be they square, rectangular, circular etc;

2) The location where the work is to be carried out, be it industrial,

commercial, on site or off site etc;

3) The quality of workmanship required.

Promat boards can be cut on site fairly easy. However, if a large

amount of boards are to be cut, it is recommended that cutting is

carried out off site under controlled conditions as much as possible

to ensure good quality of finished edges etc.


11



A few general rules should be observed when working with

Promat boards. These are as follows.

• For industrial use and extended cutting life of tools, working with

diamond tipped saws is recommended. Experience shows that

tools with carbide teeth will provide a more than adequate cut but

the tools will wear at a faster rate.

• High speed electric tools generate very fine dust. Inhaling fine

dust can be harmful to health. Therefore, dust extraction or wet

cutting is required. Although Promat boards contain no harmful

fibres, inhalation of excessive nuisance dust can be detrimental.

Promat recommends that when cutting or drilling any fibre cement

products, appropriate face masks should always be worn.

• Slow running tools produce coarse dust or chips but are not so

efficient at cutting.

• The speed of cutting is best determined by:

- thickness of the board;

- hardness of the board;

- condition of the blade.

• The boards must be held firm during cutting to avoid slippage and

vibration which can lead to chipping of the board edges.

• The choice of the most appropriate tool for use in each country

will depend on custom, practice and local regulations.

Industrial Machines

Industrial machines are used for continuous cutting over long

periods of time, for large quantities and for high efficiency. The

following types can be identified.

Cutting With Diamond Tipped Blades

Cutting with diamond tipped blades is carried out using a high

speed electric motor (2500-3000 rpm/min. depending on the

diameter of the blade). There are two types of cutting machine:

1) Machine with fixed table and moving saw support;

2) Machine with fixed saw support and moving table.

The saw support can be equipped with several parallel saws for

multi cutting in a single pass of the blades over the boards. A

diamond tipped blade can be used in either a wet or dry state.

The disadvantage of wet cutting is the generation of a cement slurry

which forms from the mixture of the dust and water. This must be

drained off in an appropriate manner. In addition, it is necessary to

rinse the saw after each use to maintain cutting quality. Wet cutting

is not an ideal solution for Promat boards.

The boards should be cleaned after cutting to avoid leaving any

dust particle on the surface. The wet diamond saw is the most

convenient method of continuous cutting of the higher density

Promat boards such as PROMATECT®-H and PROMINA®-HD (see

PROACTIVE FIRE PROTECTION SYSTEMS Application & Technical

Manual 2007) in thicknesses greater than 15mm well as other thick

compressed or autoclaved panels. Diamond blades can be used to

cut more than one board at a time depending on the diameter of the

saw blade.

When continuous dry cutting of medium or low density products

is carried out with a diamond tipped blade, dust may adhere to

the diamonds on the teeth of the blade due to high working

temperatures. A few cuts of highly abrasive stone will clean the blades

effectively. In all cases dust extraction equipment is necessary.

Cutting can also be combined with a milling cutter to produce

bevels and tapered edges etc.

Cutting With Carbide Blades

Tungsten carbide tipped saws can be used with either a high or

low speed electric motor. The cutting is done in a dry state so

dust extraction is essential. The tungsten carbide teeth of the saw

have a shorter life span than diamond tipped blades but they can

be sharpened.

Semi-industrial Machines

The semi-industrial machine described below is for dry cutting

only. The machine will work with both high and low speed

electric motors.

The high speed electric motor with diamond tipped blades can be

used for other building materials such as concrete, natural stone,

brick etc. The low speed motor with tungsten carbide tipped blades

is better suited for cutting fibre cement materials.

Cutting Promat boards using this machine provides a neat cut and

smooth edges.

The major advantages of this machine are:

• Dry cutting;

• High efficiency;

• High quality of cutting;

• Several boards can be cut at once;

• The boards need not to be secured during sawing.

Continued from previous page

On-site Machines

While working on site, hand tools and low speed electric tools are

generally recommended. When high speed electric tools are used,

dust extraction is essential.

Power tools with dust extraction equipment

Sawing machines such as FESTO, Bosch, Makita etc. work with a

tungsten carbide tipped saw blade on a low speed electric motor

(250 rpm) and moves over a fixed working table.

It is a typical machine for occasional use on site producing very

good results and is capable of cutting boards with maximum

thickness up to 20mm.

A vacuum cleaner is recommended for use while cutting especially

when using power saws. As an additional safety precaution, always

wear eye, ear and dust protection when using power tools of any

description.

A portable version of the working table is available for the

convenience of board cutting at site, as illustrated above.

While working with power saws, the following important points

should be noted:

• Ensure that the boards to be cut are continuously and well

supported on either side of the cut;

• A straight edge should be clamped in position to guide the cutting

operation;

• Care must be taken to ensure the tool remains against the straight

edge during the cutting operation;

• The cutting rate should be such that the blade is not labouring or

over-heating. Normally the feed speed would be slower than for

natural timber.

Scoring knife

This tool is equipped with a tungsten carbide tipped point. It is

suitable to use for panels up to 8mm thick. A straight edge is used

to guide the knife. Several passes are required on the board surface

to produce a groove. The final break is obtained by applying

pressure on the unsupported part of the board. The cut is relatively

neat but the edge should be finished with glass paper or a plane.

Jigsaw

This is applicable for panels up to 25mm thick. The panels can be

cut easily with a jigsaw to form various shapes. Saws with special

hardened teeth are available for cutting Promat boards. As with all

power tools, care should be taken to cut within the capacity of the

tool and blade. Do not force the cutting speed.

Hand saw

Hand sawing is suitable for general cutting operations and for small

cuts, notchings or small penetrations. However, this method of

cutting is time consuming. As always, the fastest method of cutting

is to allow the saw to work at its own speed. Trying to force the tool

to cut faster merely blunts the teeth.

Rasp/Surform

A rasp or surform can be used for edge finishing where necessary

in order to trim away rough edging. For fine edge finishing, dress the

edges with fine glass paper.

Drilling

Drilling can be achieved either by hand or any conventional power

drill with or without dust extraction. For best results, the boards

should be firmly supported behind the location of the holes.

Generally, when working on Promat board products, the use of drills

with point angles of 60O to 80O rather than the more usual 120O type,

are preferable and more efficient.

Flush Jointing Between Boards

PROMATECT® 100 boards can be simply butt jointed with sheets

having square, bevelled or chamfered edges. If required, a filler may

be used to finish joints before decoration.

Flush Jointing

Flush jointing is applicable to most partition and ceiling

constructions. However, in some instances it may be also

applicable to external wall constructions.

Generally installations of concealed framed ceiling and partition

systems require crack-free flush jointing. The method of

constructing flush joints depends very much on the skills and know-

how of the installer, as well as the stability of the supporting

construction. It is recommended that the thickness of panels used

for flush jointing should be of at least 8mm thick. Thinner boards are

allowed only when they are to be rendered with synthetic binders or

textures at a later stage. Following are some guidelines for joint

finishing in order to achieve the required appearance. For further

information, please consult Promat Technical Department.

To obtain a flush joint it is preferable that all panels have recessed

edges where they abut one other. The long edges of sheets have

pre-formed recesses, the short edges do not. It is not advisable to

have a recessed edge adjoining a square edge. It is preferable to

recess the edges of cut sheets where they have to be flush jonted.

If this is not practical, then the width of the flush jointing of square

edge sheets shall be twice the width of the flush jointing for

recessed joints.

When the boards are ready for joint treatments, follow the steps

below to obtain the required finish.

a) After the installation of the boards, wait until the moisture content

in the sheet is equivalent to that of the air. This would normally

take approximately 24 hours to achieve. Once this equilibrium

moisture content is achieved, moisture induced movement will be

lower, thus there will be less risk of joints cracking.

b) Always work with clean tools and containers.

c) The work should be carried out in environment where the

ambient air temperature is at least 5OC or above.

d) Prepare the joint filler as per instructions prescribed by the

manufacturer. Always use clean water.

e) Fill the bevel with sufficient joint filler (see illustration below).

f) Apply a layer of reinforcing paper tape over the filler and cover

the complete surface of the tape with excessive amount of joint

filler (well-embeded) using a trowel.

g) Remove any irregular surfaces on the joint by scraping away

using the back of the trowel.

h) Apply a second layer of joint filler with wide trowel.

i) Wait until it is completely cured.

j) Depending on the level of finishing required, an eventual last

layer of joint finisher can be applied with a 280mm wide

(preferably curved) trowel.

Joint fillers normally manufactured for use with plasterboards are

suitable for flush jointing of Promat board when installed within

dry areas.

It is recommended that areas to which filler is to be applied should

be pre-wet so that as boards gradually dry, tensile stresses and

sufficient adhesion are created in the joints.

Pre-wetting the boards ensures they do not rapidly absorb the

moisture from the filler, thus avoiding occurrence of cracks in

the joint.

Plastering

PROMATECT® 100 boards have high suction and while successful

skim coats are easily obtained, some care is capability needed to

retard the rapid drying of plaster coats, especially in areas of high

temperature. If plastering is essential, please consult the Promat

Technical Department.

It is recommended that a small test area is plastered initially to

ensure that the boards have been adequately sealed. It is advisable

that the use of self-adhesive or hessian scrim applied over joints and

internal angles is considered. Paper scrim is not recommended.

NOTE: The bonding agent and plaster manufacturer’s recom-

mendations must be followed at all times.

Tiling

PROMATECT® 100 boards can be tiled, provided due consideration

is given to the installation of the boards and the requirements for

additional framing prior to applying the tiles. It should be carefully

noted that Promat systems are used for their fire resistance

properties. Therefore placing additional weight on the system, such

as ceramic or marble tiling for instance, can have a significant effect

on the overall performance of the system.

It is for this reason that additional framing is required for partition

systems etc. which are to bear the weight of tiles and still maintain

their fire performance.

As a general rule of thumb, partition systems to be tiled should be

constructed with framing at nominal 450mm centres in both vertical

and horizontal orientations. Minimum board thickness can apply.

While tiling these boards can be successfully achieved, care needs

to be taken in sealing the boards thoroughly before applying any tile

adhesive, due to the very high suction the boards have and which

in turn accelerates the setting time of the tile adhesive. Please

consult the Promat Technical Department.

Painting

All coatings should be supplied by a reputable manufacturer and

their recommendations regarding surface preparation, sealing and

finish coating should be followed at all times.

PROMATECT® 100 boards have an attractive, smooth finish but if

required can be painted with emulsion or oil based paints. With

water based paints, a diluted first coat should be used. For oil

based paints use a universal primer. An alkali resisting primer is

not required.

Depending upon the type of finish used, it should be noted that in

certain circumstances, i.e. when viewed in a glancing light, some

minor surface imperfections may show.

Structural Steel General Information /

Definition & Calculations For Section Factor

Introduction

Numerous research programmes show that some types of fully

stressed steel sections can achieve a fire resistance of 30 minutes

without any additional protection materials being applied. However,

these apply to a limited number of steel sections only, based on

the allowable Section Factor Hp/A. Section Factor is a common

term used in fire protection for steelwork and is discussed in

detail below.

Typical building regulations usually require certain elements of

structure to be fire resistant for up to 120 minutes or up to a

specified minimum period of time. The thickness of any fire

protection material depends on a number of factors, such as:

• Duration of fire resistance specified;

• Type of protection used (e.g. board, paint, spray etc);

• Perimeter of the part of steel section exposed to fire;

• Shape and dimensions of the steel section.

To determine how these various factors affect the fire resistance, all

Promat products and systems have been tested at nationally

accredited laboratories around the world to a variety of standards,

e.g. BS476: Part 21, AS1530: Part 4, DIN 4102 and ASTM E119.

Tests carried out in accordance with AS1530: 4 and BS476: Part 21

are performed on both loaded and unloaded beams and columns

which are clad with fire protection material. Steel surface

temperatures are monitored with thermocouples to assess the

performance of the cladding. Steel that is stressed in accordance

with the design guides BS449 or BS5950: Part 1 (Australian

equivalent AS4100), begin to lose their design margin of safety at

temperatures around 550°C. The table at above right shows how

the strength of steel reduces as temperatures rise.

strength factor

Example: At 700°C, the effective yield strength of Grade 43 (S275) steel is

0.23 x 275 = 63.25N/mm2.

The above is extracted from the ASFP publication “Fire Protection for Structural

Steel in Buildings”, commonly known as “The Yellow Book”.

A range of unloaded sections are also tested to obtain data for

analytical calculation with the aid of a computer, to measure exactly

how much protection is needed for the most common steel

sections and for providing fire resistance for different time periods.

IMPORTANT NOTE: When using Promat protection systems for

structural steelwork, conservative limiting temperatures of 550°C

and 620°C are referred to for columns and beams respectively and

are in general use throughout this section. Apart from temperature

data, the fire tests also need to demonstrate the ability of cladding

to remain in place, usually described as “stickability” of the material,

for the maximum duration for which the protection may be required.

The availability of thin boards and the low weight of Promat

systems, plus the possibility of prefabrication, ensure maximum

cost-efficiency.

Section Factor (Hp/A)

The degree of fire protection provided depends on the Hp/A Section

Factor for the steel section. The Hp/A factor is a function of the area

of the steel exposed to the fire and the mass of the steel section.

The higher the Hp/A, the faster the steel section heats up and so the

greater the thickness of fire protection material required.

It should be noted that in recently published European design

standards, the section factor is presented as A/V which has the same

numerical value as Hp/A. A/V measures the rate of temperature

increase of a steel cross-section by the ratio of the heated surface

area to the volume. It is likely to gradually replace the use of Hp/A

(also sometimes referred to as ESA/M or Exposed Surface

Area/Mass) in the future.

Depending on type of material used for protection, the calculation

method for Hp/A value may differ. Generally there are two methods

of construction for the protection materials. These are box

protection and profile protection.

Box Protection

For box protection, Hp is the sum of the inside dimensions of

the smallest possible rectangular or square encasement of the

steel section (except for circular hollow sections) as shown on

pages 18 and 19.

Where a steel section abuts or is built into a fire resisting wall or

floor, the surface in contact with or the surface within the wall or

floor is ignored when calculating Hp.

However, the value A is always the total cross-sectional area of the

whole steel section.

Profile Protection

Encasements following the profile of the steel section will generally

have a higher Hp/A section factor than a box encasement. One

exception is circular hollow sections as detailed in the following

pages. If required, please contact a local Promat Technical

Department for further advice.

The serial size and mass per metre of most steel sections are

available in tables from steel manufacturers. Sometimes such tables

also provide Hp/A values calculated for 3 or 4-sided box protection.

Upon request, Promat Technical Department will provide assistance

in calculating Hp/A section factors and required material thicknesses.

As a general guide, please refer to pages 18 and 19. Below is an

example of calculation section for a beam box protection.

Example: Steel beam, serial size 406mm x 178mm x 54kg/m

to be encased on 3 sides

Serial size = 406mm x 178mm

Actual size = 406.2mm x 177.6mm

Hp = B + 2 D

= 177.6 + 402.6 + 402.6

= 982.8mm (0.9828m)

A = 68.1cm2 (0.00681m2)

Hp/A = 0.9828 ÷ 0.00681

= 144.3

= 145m-1

The value of A, the cross-sectional area, can be obtained either

from steelwork tables or by accurate measurement. However, if

the mass per metre is known, the Hp/A value can be calculated

as follows:

Hp=

7850 x Hp

A W

Where W = Mass of per metre (kg/m)

Where 7850 = Nominal density of steel

Where Hp = Heated Perimeter

NOTE: Calculation for profile protection can be simplified by

ignoring the thickness of the steel section. As such, the value

obtained is slightly conservative. For instance, a universal beam

protected on all 4 sides, the calculation of perimeter Hp is simplified

to 4B + 2D. The shape of the steel section can also play an

important role when determining the require thickness of a

protection material. On the following page is some reference

information. For details on steel profiles not outlined here, please

consult Promat Technical Department.

Structural Steel Definition & Calculations For Section Factor

Castellated Sections / Cellform BeamsThese heat up faster than the original section from which they were

produced. Protection thickness should therefore be 20% greater

than those calculated from the Hp/A value of the original section

from which the castellated section is formed.

However, it should be noted that the above information is now

considered somewhat out of date and a new, more scientific

approach is applied for the protection of castellated sections. The

following is taken from Fire Protection For Structural Steel In

Buildings, 4th Edition published by the ASFP (see www.asfp.org.uk).

The recommended method of obtaining the section factor (Hp/A) for

castellated sections is now amended as follows. The

recommendation from the Steel Construction Institute, as published

in RT1085, that for castellated sections and cellular beams

manufactured from all rolled steel sections and from welded plate,

the Section Factor for both passive and active fire protection

systems should be calculated as:

Section factor [m-1] = 1400/t

Where t = the thickness [mm] of the lower steel web

and applies for beams made from all

steel rolled sections and from welded

steel plate.

It should also be noted that there are a number of conditions

attached to the use of this calculation method, and these are

detailed in the ASFP “Yellow Book” publication mentioned above.

It should further be noted that the above rule does NOT apply

to intumescent paints, where the ability of a reactive coating

product to provide protection to the critical areas of the beam

is very product specific. Individual protection products,

normally quite similar in performance when compared on the

basis of rolled steel sections, may require radically different

thicknesses for the same cellular beam.

Structural Hollow SectionThe same thickness of Promat board materials can be used on

hollow sections as on ‘I’ sections of the same Hp/A value. This rule

does NOT apply to intumescent products.

BracingBracing is included in a structure to give resistance to wind forces

and provide overall stiffness. Masonry walls and steel cladding

contribute to structural rigidity but these are rarely taken into

account in design. Also, the probability of a major fire occurrence

concurrent with maximum wind load is remote (see BS5950: Part 8

or AS 4100). It seems unreasonable therefore to apply the 550°C

steel temperature criteria to bracing. While each case must be

judged on individual merits, protection to bracing is generally not

necessary, but where it is required the Hp/A value of the bracing

section or 200m-1 should be used, whichever is the lesser.

Lattice MembersAs the determination of the protection necessary to protect lattice

members requires broad consideration of the lattice design, please

consult a local Promat Technical Department for advice concerning

such steel sections.

Partially Exposed MembersWhere columns or beams are partly built into or are in close contact

with walls or floors, the protection afforded to the steelwork by the

wall or floor should be taken into account. In those instances where

the steel section sits within or against masonry or concrete

constructions, this will give protection to the adjacent surface of the

steelwork. Thus, for the purpose of determining the heated perimeter

(Hp), this should be taken as only that part of the steel section which

is exposed. It should be noted that where the steelwork penetrates

both sides of a fire resisting construction, i.e. a wall protruding into

a space which has an open end, simultaneous attack from fire on

both sides may occur on columns partially exposed within the wall.

In such a situation, the section factor should be calculated based

upon the sum of the areas exposed to fire on either side of the wall

and the total volume of the steel section. Note that separating

elements are generally required to offer a performance including the

insulation criteria of 140°C/180°C. Therefore, where a steel section

passes through a separating element and is exposed on both sides,

consideration must also be given to providing sufficient protection

not only to maintain the temperature of the steel section below

550°C but also to ensure the surface temperature on the unexposed

face does not exceed the 140°C/180°C insulation criteria of the

separating element. Due allowance for any expected building

movement should also be considered.

External Lightweight WallsWhere the structural elements form portal legs supporting a

lightweight external wall, the insulation performance required of the

wall may contribute to the protection of any column flange falling

within the thickness of the wall. In such cases, please consult the

local Promat Technical Department to confirm the board thickness

and which areas of such columns should be protected.

Internal Lightweight Walls/PartitionsWhere a column or beam is built into a fire resistant lightweight wall

or partition, the protection to the steelwork can generally be

designed on the assumption that only one side of the wall or

partition will be exposed to fire at any one time. The wall or partition

should be adequately secured to the column in such a way as to

ensure the wall or partition will not apply stress on the protection

encasement. Due allowance for any expected building movement

should be considered.

FloorsWhere beams are wholly within the cavity of a timber floor protected

by a PROMATECT® ceiling, test evidence shows that the cavity air

temperature of the floor is such that the beam will be adequately

protected to the same fire resistance by the ceiling that protects the

floor. Where the beam is wholly or partly below the line of the

PROMATECT® ceiling, the Hp should be based upon the portion of

the steel beam that is below ceiling level.

Beams Supporting Composite Floors

With Profiled Metal DeckingA series of fire resistance tests, jointly sponsored by ASFP

members (including Promat) and others, demonstrates that it is not

always necessary to fill the void formed between the top flange of

a beam and the underside of a profiled steel deck.

Recommendations based on the research have been published by

the Steel Construction Institute (UK) and for decks running

perpendicular to the beams, are as follows:

Dovetail decks

Voids may be left unfilled for all fire resistance periods; unless a fire

resisting wall or partition is located beneath the beam.

Trapezoidal decks

Generally, voids may be left unfilled for up to 60 minutes fire

resistance. Also, for 90 minutes if the board thickness used is

appropriate for the Hp/A + 15%. Care should be taken to ensure

that if the voids are unfilled, the main encasement will need to be

adequately secured. Please refer to Promat Technical Department

for advice.

For periods over 90 minutes the voids should be filled.

In all instances, voids should also be filled if a fire wall is located

beneath the beam, for all fire resistance periods. These

recommendations apply to board encasements. The trapezoidal

steel deck slab should be designed to act structurally with the

beam. If this is not the case, the voids should be filled for all fire

resistance periods.

How To Specify

1. Choose the material to be used.

PROMATECT® 100

A white board with a flat and smooth surface that provides high

insulation performance with minimum thickness, offering up to 150

minutes fire protection.

2. Determine the period of fire protection required.

3. Determine the section factor (Hp/A) of the steel section.

See opposite page.

4. Using the Hp/A factor and the required fire protection

period, determine the board thickness and fixing details.

Please refer to page 32.

NOTE: For 90 and 120-minute applications using single layer board thickness, please consult the tables on page 32. In some instances, the

use of single layer board results in lower permissable Hp/A to board thickness ratios.

This table provides information relating to the 3-sided encasement

of steel beams where a concrete deck is directly supported on the

top flange of the beam, where the concrete acts as a heat sink and

where the beams are generally not fully loaded. Therefore a

temperature of 620OC is considered appropriate.

Where the beam supports a floor of a different construction other

than plain concrete, this failure temperature may not be applicable.

If in doubt, please consult your structural engineer or your local

Promat Technical Department.

NOTES:

• All above tables provide information for applications providing 30 to 150 minutes fire resistance performance using single layer

PROMATECT® 100 up to 25mm thick. For greater thicknesses, double layer system is recommended.

• For use of single layer PROMATECT® 100 in 30mm or greater thickness, please consult the local Promat Technical Department.

This temperature of 620°C as per Table 7 applies only to the protection of beams where the structural element forms part of a composite floors

system, such that the beam and the floor move in concert and not as separate elements. The floor system must be of concrete construction.

This table does not apply to beams which are to be protected on four sides, or beams which are not permanently fixed to the concrete slab

above. Beams which are free to move independently or the concrete floor slab above, or where the floor is not formed of concrete should be

protected to 550°C using Table 6 above.

Architectural Specification

Only general information can be provided in this document. It is

recommended that the local Promat Technical Department be contacted to

confirm details not covered here.

Fixing methods are suitable for steel sections up to 686mm deep and 325mm

wide. For larger sections and when protecting multiple sections within a

single encasement, please consult the local Promat Technical Department.

Where a column cladding box encasement abuts a beam protected with a

profiled fire protection system, e.g. sprayed material, the column webs

should be sealed at the junction using PROMATECT® 100.

While the PROMATECT® 100 system is not recommended for the fire

protection of external steelwork, providing it is fixed in dry conditions, the

casing can withstand exposure to light rain or site water spillages for a few

weeks, after which it should be protected from exposure to water. If the

cladding is likely to be severely soaked after installation, protection from

weather should be employed.

to a fire engineered design. Please consult the local Promat Technical

Department for further details.

The following are standard architectural specifications for structural

steelwork protection using PROMATECT® 100. NOTE: Fixing PROMATECT®

100 can be achieved by screw fixing to steel framing or board to board using

boards of thickness 20mm or greater. Board to board can also be staple fixed

according to table below.

The end user must determine the suitability of any particular design to meet

the performance requirements of any application before undertaking any

work. If in doubt, the advice of a suitably qualified engineer should first

be obtained.

Partitions General Information

Introduction

Partitions and external walls are used to separate buildings, enclose

compartments and contain fire to provide a barrier to the passage

of fire from one side to the other and are able to satisfy each of the

relevant fire resistant criteria (integrity, insulation and, if the wall is

loadbearing, load bearing capacity) from either side for the

prescribed period. The application of partition and external wall

systems using Promat boards covers both non loadbearing and

loadbearing in commercial, industrial, institutional, residential and

high-rise constructions, or in the restoration of existing buildings.

Promat’s internal partition systems require less material to achieve

similar fire resistant level when compared to the industry average

wallboard partition systems. The single layer board application

leads to simplified construction methods over other equivalents

hence increased productivity and reduced overall installation cost.

These partition and external wall systems have been developed by

Promat International (Asia Pacific) Ltd. to satisfy standard

requirements for intended applications. Such considerations include:

Time & Cost Effectiveness

Single layer application reduces installation cost and time

compared to traditional wallboard partitions.

Slim Walls

Partitions can be as thin as 40mm.

Lightweight

Lighter loads on structures compared to industry average wallboard

partition systems for equivalent fire resistance.

Thermal Resistance

Excellent thermal resistance performance.

Impact Resistant

PROMATECT®-100 partition systems have been tested and

assessed for impact and static loading to satisfy specification CI.8

of the Building Code of Australia (BCA 2006). PROMATECT®-H

partition systems have been tested for resistance to impact, stiffness

and robustness in accordance with the criteria of BS5234: Part 2.

Acoustic Performance

Tested and assessed to a range of standards, including ISO140-3

1995, ISO717-1 1996, AS1191 2002, AS/NZS 1276.1, BS5821 1984

and BS2750: Part 3: 1980, to meet the needs of industry. Please

refer to pages 41 and 42 for details.

Fire Resistance Performance

Promat partitions and external wall systems have been extensively

tested and assessed in accordance with BS476: Part 22 and

AS1530: Part 4 to satisfy the integrity, insulation and where

applicable loadbearing capacity (structural adequacy) criteria.

General Design Considerations

The following points are some of the factors which should be

considered when determining the correct specification to ensure

a partition or external wall will provide the required design

performance under both fire and ambient conditions. Further advice

can be obtained from the local Promat office.

1. Studwork Design

The design of studwork should be adequate for the height of the

partition. The studwork details given in the following specifications

will be suitable up to the maximum heights stated. For greater

heights the dimension of the framing members could change

depending on the factors such as movement and deflection and

local approvals. Larger or more frequent frame sections will often

improve the fire and structural performance.

The studwork shall be appropriately designed for the applied loads,

e.g. wind load, and where applicable structural load in the case of

load bearing systems. The framing for the partition systems must be

securely fixed to a substrate that has an equal or greater fire

performance than the designed partition. All fixings must be non-

combustible and must be those listed in the approval documents.

The design shall be in accordance with the relevant Australian,

British and/or International Standards.

2. Non Loadbearing Partitions

Non loadbearing partitions and external wall systems using Promat

boards can be generally divided into framing systems consisting of

steel or timber studs and solid partitions. For steel stud systems,

selection of suitable stud size shall be in accordance with the

maximum partition height given in the stud selection tables. The

partition systems in the following pages, where stated, are designed

for lateral loads of up to 0.25kPa using the composite action of the

frame and boarding.

3. Loadbearing Partitions

Loadbearing capacity of featured partition systems in this

handbook are calculated in accordance with BS5950-8: 2003 and

AS4600: 1996 for load cases defined by AS1170: 2002. The

maximum load bearing capacity is given in kN for a given

partition height taking into account the reduction in steel strength at

elevated temperature.

Studs are located at 600mm maximum centres with noggings as

detailed in Studs Table on page 50.

Loads considered in this manual are for axial compression only.

Wind and other loads have not been taken into consideration.

For further information on these loads, please contact Promat


4. Deflection

Where differential movement is expected between the floor or beam

above the construction, and/or the floor below, it is generally

advisable to incorporate a deflection head track to ensure undue

stress is not placed upon the partition. This also allows for the

sagging and deflection a floor or structural steel beam will suffer

under fire conditions. Even concrete floors will suffer considerable

deflection under fire if exposed for any considerable duration.

Some form of movement joint is also required to allow for the

expansion of the studs under fire conditions. A partition will also

bow in its centre. As the wall bows, it will naturally get shorter. For

this reason alone, use should be made of a top track with long side

legs. This will allow the stud to bow and as a result drop down,

without the studs dropping out of the head track.

5. Movement Joint

Movement stress from dimensional changes due to varying

temperature or moisture conditions can cause cracking and other

symptoms of distress in partitions. Other external forces such as

impact or vibration can directly affect the structural movement of

partitions. This movement can be controlled through a variety of

design techniques such as introducing perimeter relief and slip

connections to reduce the transfer of stress from the structure to

other building sub-elements and/or through the use of expansion

joints, control joints and construction joints.

In a partition, expansion joints are needed when the partition abuts

a rigid mass. A vertical movement joint should be located at

maximum 10m centres in long runs of partition. However, by

introducing a control joint into a fire-rated partition, it does create

an opening for flame and temperature transmission and therefore

has to be properly treated with approved fire-stopping material.

Please refer to page 86 for further details on movement joints.

Steel Frame Components

Board Fixing

Promat boards may be installed horizontally or vertically.

For steel stud partition system, joints in the boards must be

staggered between either side of the framing with all the joints

located at a framing member. The boards may be fixed to the studs

using No.8 Bugle head self drilling and self-tapping screws of a

length appropriate for the board thickness. Needle point screws are

normally used to fix boards to light gauge steel frames up to

0.8mm. Drill point screws are generally appropriate for heavy gauge

steel frames from 0.8mm to 2.0mm.

For solid partition system, joints between the adjacent boards must

be staggered by at least 300mm. First layer of the boards are to be

fixed to the perimeter angle with 35mm long x No.8 self-drilling and

self-tapping screws. The subsequent layer of the boards is to be

stitched to the preceding layer with 40mm long x No.10 laminating

screws, as well as fixing to the perimeter framing.

When a timber frame is used, Promat boards are fixed to the

framework using No. 6 wood screws of a length appropriate for the

board thickness at maximum 250mm centres, a minimum of 12mm

from the board edge. Minimum edge distance to fasteners and the

maximum spacing between screw must be maintained. Please refer

to system detail for screws spacing requirements.

Internal and external corners may be set using a perforated

metal corner bead fixed to the board linings at not more than

500mm centres.

Components Selection

Construction of Promat fire rated steel stud partitions can be achieved using Rondo stud and track components. Other steel components of

equivalent performance can of course be used but it is the responsibility of the manufacturer of the component to substantiate equivalent

performance with the recommended component.

Tracks At Deflection Head & Floor

The main function of the ceiling and floor tracks is to hold the studs

in position until the board is fitted. They provide a friction fit of

the studs and also act as a slip joint to allow for any movement in

the structure.

The track sections basically come in two profiles. A standard track

has a nominal 32mm flange while the deflection head track has a

nominal 50mm flange. However, head tracks with wider flange are

available but they have to be specially designed for instances

where clearance for expansion at the head track exceeds 20mm.

No clearance for expansion is applicable at the head track for a loadbearing partition.

Track sections should be fixed at maximum 600mm intervals to the supporting structure. Fixings should be located not more than 100mm from

either end of the track section.

6. Caulking & Service Penetrations

To maintain the fire performance, and where applicable the acoustic

performance of the partition system, gaps at perimeter must be

appropriately filled with suitable caulking material. PROMASEAL®

AN Acrylic Sealant or other tested fire and acoustic rated material

of equivalent or better performance must be used.

Care needs to be taken in detailing a suitable fire-stopping system

around any penetration of the partition by services to ensure a) the

fire-stopping material remains in situ and b) fire and smoke do not

penetrate the partition.

Allowance should be made for thermal movement of the services in

both ambient and fire conditions to ensure loads are not applied to

the partition. Some examples of service penetrations include

electrical cables, conduits or wires, switches and power outlets,

plastic and metal pipes, air-conditioning and ventilation ductwork.

Further guidance on the sealing of service penetrations can be

obtained in Chapter 5 of this handbook.

7. Fire Doors & Glazing

Tested or assessed door and/or glazed assemblies should always

be used. All and any doors or glazed elements with a fire resistant

wall should be shown, by fully compliant testing within to the

appropriate standard, to be capable of providing at least an equal

fire performance to the wall itself. This means fire doors should be

tested in lightweight partition systems, not just in masonry. In most

cases additional framework will be required to prevent loads being

applied to the partition. Careful detailing is needed around the

perimeter of any door or glazed assembly. Further guidance on the

detailing at fire doors and glazing can be obtained on page 83.

8. Partition Junction

Care must be taken to ensure that partition corner junctions and

intersections are stable for both fire and ambient conditions.

Framing at these locations has to be mechanically fastened

together. Further guidance on the detailing at these junctions can

be obtained on pages 87 and 88.

Steel Studs

The recommended Rondo studs come in thicknesses of 0.50mm, 0.55mm, 0.75mm and 1.15mm. The

0.50mm to 0.75mm studs have a standard 25mm bell-mouthed service holes for electrical cabling. For

the 1.15mm stud, punched round holes are processed at designated centres along the stud.

Spliced extensions are possible in situations where the overall height of the partition is more than the stud

length. The 0.50mm to 0.75mm studs may be boxed and the 1.15mm studs may be spliced back-to-back.

For greater rigidity at fire resistant glazing and door openings, and also at locations where extra load

carrying capacity is required, studs of 0.50mm to 0.75mm may be boxed and studs of 1.15mm may be

fixed back-to-back. See guide below on spliced studs and stiffening framing.

Guide to fixing spliced studs for partition heights up to 7000mm

NOTE: The splice location % refers to the height of the partition. For

example, taking a partition 10,000mm high, a 10% splice location

would be located within 1000mm of the top or bottom of the wall.

A 25% splice location would be within 2500mm of the top or

bottom of a 10,000mm high wall.

• Splices should alternate top & bottom of wall.

• Do not place splices between 25% and 75% of wall height.

• Splicing of studs is recommended for non-loadbearing

partitions only.

• Where splicing is not possible due to the height, use

fully boxed sections.

Nogging Track

Noggings are necessary to provide bracing to the partition studs

and preventing the studs from twisting when fitting the lining

boards. The noggings are to be screwed, rivetted or crimped to

both flanges of the studs. Continuous nogging tracks 0.55mm and

0.75mm are available from Rondo. This nogging track can be fitted

to the stud framing in one length. Alternatively, individual noggings

may be cut from the track. Noggings of 0.75mm can be used with

1.15mm studs.

Nogging track framing

Track to be fastened to substrate floor and ceiling with M6 anchor

bolts 40mm long at maximum 600mm centres. Studs can be

installed vertically at 600-610mm centres (distance depends on the

size of the boards use). See details of Bottom track fixing at right

Timber Frame Components

Timber Frame

Timber has very good performance in fire. Timber does burn but at

a relatively slow and to a predictable depth known as the charring

rate. This is one major advantage of using timber over steel

because the fire resistance of timber elements of construction may

be calculated based on a predictable charring rate.

Timber also has a very low thermal conductivity value and hence

does not heat uniformly. Therefore, timber material a few millimetres

inside the burning zone is just warm. The formation of a self

insulating char resists further heat penetration.

Unlike materials with a high thermal conductivity materials such as

steel, there are less problems associated with expansion or loss of

strength over the whole section in timber. This means that, in some

instances timber retains its structural integrity better than steel.

There are many different types of timbers and they all char at

varying rates. Higher density timbers char more slowly than those

of lower density. Denser hardwoods used for structural purposes,

such as jarrah, teak, keruing and greenheart, char at a rate of

15mm in 30 minutes. Lower density (< 650kg/m3) softwood timbers

such as Western red cedar or Pinus Radiata is estimated at a

charring rate of 25mm in 30 minutes.

Timber Studs & Cross Noggings

The frame used in the timber stud partitions typically consists of

90mm deep x 45mm wide softwood timber. The fire performance of

the partition system accounts for the loss of the timber section due

to charring effect without compromising the fire performance of the

partition.

Where the boards are to be installed with their long edges vertical,

the studs are located at 600mm maximum centres (dependent on

board width) with cross noggings at 1250mm centres. Where

the boards are to be installed with their long edges horizontal, the

studs are located at 600mm centres with cross noggings at

1250mm centres.

The cross noggings may be fixed to the studs using nails or

woodscrews of at least 100mm long in a manner shown in Fixing

method 1 or 2 at right. Either method can be adopted to fix the

cross noggings.

Top & Floor Plates

The top and floor plates are to be of the same material and

dimensions as the studs. They are to be secured to the surrounding

structure with at least M6 x 100mm long anchors at nominal

600mm centres with the drilled depth into the concrete structure of

at least 40mm. Polyamide nylon anchor sleeves may be allowed for

use with timber framing.

The vertical studs may be fixed to the top and floor plates using

either nails or woodscrews of at least 100mm long in a manner

shown in Floor plate fixing at bottom right.

Loadbearing Partition

Where a partition is loadbearing, the required size of the stud shall

be calculated by a suitably qualified structural engineer. Care

should be taken to ensure that the loadbearing partition has been

designed to resist all applied loads and in accordance with BS5268:

Part 4, AS1720: Part 1 or AS1684. Generally, the fire performance

and the load carrying capacity will improve by increasing the cross-

sectional dimensions of the timber elements and/or decreasing the

stud spacing.

Partitions Acoustic Design

Acoustics In Building

Sound is an energy generated by a source, transmitted through a

medium and collected by a receiver. It can be pleasant to be heard,

such as music and speeches etc, while some, such as scratching

a glass surface with a sharp object, are irritating. This offensive

sound is commonly termed noise. The acoustic design of buildings

can be divided into two basic requirements, noise control and

room acoustics.

Noise control relates to the quantity of sound with an objective to

ensure the sound level does not adversely affect the comfort of

building occupants. This involves control of sound produced in

a room, such as telephones ringing, as well as limiting the noise

entering from other rooms or outside the building. A common

solution targeting this problem is the introduction of sound

absorption systems.

Room acoustics relate to the quality of sound with an objective to

enhance the quality of desired sound within a room. This involves

factors such as speech intelligibility and perception of musical

clarity. The most widely applied solution employed by building

designers is the use of a sound insulating system.

A point worth noting is that although both noise control and room

acoustics have independent objectives, they are however inter-

related in practice. As this manual covers partition and ceiling

systems, the following concentrates only on issues related to sound

insulation which involves transmission loss (TL) of airborne sound.

Sound Transmission & Classification

The sound transmission loss of a building element, such as a

partition, is a measure of how much sound is reduced as it passes

through the barrier, expressed in dB or decibels, the unit used to

quantify sound. The generally accepted term for the single number

ratings for sound transmission loss is the Sound Transmission Class

or STC (ASTM E413). This is determined by comparing the TL value

to the reference curve in ASTM E413. Generally the higher the STC

value, the better the performance of the system. The following table

provide a rough idea of what various STC levels mean in terms of

privacy afforded.

STC Privacy afforded

25 Normal speech easily understood

30 Normal speech audible, but unintelligible

35 Loud speech understood

40 Loud speech audible, but unintelligible

45 Loud speech barely audible

50 Shouting barely audible

55 Shouting not audible

Source: U.S. Dept of Commerce/National Bureau of Standards Handbook.

“Quieting: A Practical Guide to Noise Control”.

Another widely accepted equivalent term is the Weighted Sound

Reduction Index or Rw (ISO 717: Part 1 or BS 5821: Part 1). It is

determined in a similar manner but instead of TL values, an

equivalent Sound Reduction Index (R or Rw) is used.

Note should be taken that results obtained in STC and Rw may

have a ±3dB deviation from one another.

Unlike laboratories where elements of construction are subject to

testing in perfect acoustic conditions, the majority of buildings have

a far greater range of access points and channels where sound can

travel. As such it is highly unlikely that the acoustic performance of

a sample measured in a laboratory will achieve the same level when

installed in a building. It is therefore imperative that specifiers

should give great consideration to ensuring compatibility between

adjacent and/or connecting elements of construction and the main

building structure. Depending upon the type of construction and

system used, a shortfall of between 5% and 10% can be expected

when comparing actual site installations to the performance of

laboratory specimens.


With modern design concepts and technology in building

construction, acoustic performance within buildings has become an

important element for consideration by building designers. There

are many factors involved in establishing an ideal noise level for any

particular building space, part of which are as follows:

• To avoid fatigue induced by noise;

• To prevent distraction or disturbance;

• To maintain a good communication & listening environment.

Heavy walls such as concrete have good transmission loss.

However, there are some drawbacks which limit its performance.

The law of mass dictates that a wall will increase its transmission

loss by only 5dB for every doubling of mass. Therefore, a single

100mm thick concrete wall of 2300kg/m3 density might have an

STC 45 rating whereas a 200mm thick concrete wall would only

achieve STC 50 for a doubling in mass. For most owners and

builders, a wall of this size and weight is not desirable. Cost may

more than double and the decibel-per-dollar achieved is clearly not

acceptable. This limitation can be easily overcome by using a

lightweight system, i.e. the partition system, where it is more

practical to utilise principals such as air cavity, resilient mountings,

sound-absorbing core materials or a combination of these

principals without the large increase in mass required for solid walls.

Following are some common practices that are effective for noise

control and room acoustics.

1. Double-studding & Air Cavity

With typical drywall partitions, sound striking at the wall surface is

transmitted through the first surface material into the wall cavity. It

then strikes the opposite wall surface, causing it to vibrate and

transmit the sound into the air of the adjoining room. This is

termed airborne sound. When the sound strikes the wall at the stud,

sound is transmitted direct through the stud and is termed structure

borne sound.

The principal of double studding basically means separation of two

panels of a drywall partition into a double-leaf wall, integrated with

appropriate air spacing (cavity) between the leaves. The

introduction of an air-space provides some form of separation or

discontinuity between the two wall faces in a double-leaves wall.

As an example, a double stud

partition creating an air cavity

eliminates direct mechanical

connection between the surfaces.

The sound transmission is reduced

by breaking the sound path. In

addition, the air cavity provides

vibration isolation between the

two sides. Sound in one room

striking one side of the wall causes

it to vibrate but because of the

mechanical separation and the

cushioning effect of the cavity,

the vibration of the other side is

greatly reduced.

2. Sound-absorbing Core Material

Sound absorption is the effectiveness of a material at preventing the

reflection of sound. Generally, the more sound absorption, the fewer

echoes will exist. The sound-absorbing core used in the Promat

partition designs can be mineral or rock wool, glass wool or

polyester, depending upon fire resistance requirements.

These cores will further improve the sound isolation performance of

the wall by absorbing sound energy in the cavity before the sound

can set the opposite wall surface in motion. They will also provide

some damping of the vibrating wall surface.

Partitions Acoustic Design


3. Treatment To Flanking Paths

When working with acoustically rated systems, it is critical that strict

attention be paid to construction and detailing. The acoustic

integrity of a system can be influenced by the combination of

elements that make up the system. Single leaf and uninsulated

systems are particularly dependent on high quality of installation.

For example, if there is a gap of 5mm wide around the perimeter of

an STC 45 rated wall of 3m x 3m, the actual performance would

degrade to some STC 30. Therefore, to make acoustically rated

partitions effective, they must be airtight. Any path for air also

means there is a path for sound. In order to achieve the designed

STC rating closely, the following factors must also be taken

into account:

• Sound paths, e.g. windows, doors, floors and ceilings;

• Penetrations through walls, even above ceilings or below

floorings, must be sealed;

• Stagger the joints between multiple layers of wall boards

or ceiling linings;

• Do not use power points back to back on either side of a wall;

• Openings for return air in ceiling plenum systems must be

strictly controlled.

4. Wall & Floor Intersections

A good acoustical partition is only as good as its joint or

intersection at wall and floor, like a chain and its weakest link. If this

joint or intersection is not treated properly, the acoustical value may

be lost. Many joint defects from flanking paths allow sound to travel

via air gaps through the structure.

Acoustical sealants are the simplest means to provide a permanent

air-tight seal. They are made from materials that are permanently

elastic which will allow floor or wall materials to move, as they are

prone to do because of expansion and contraction or outside forces

such as structural movement. A permanent air-tight seal is the

most effective way to maintain the acoustical integrity of the wall.

Regardless of which system is employed, all openings, cracks and

material joints should be made air-tight with a permanently elastic

acoustical sealant.

installations, unless otherwise specified by the architects. Please

Ceilings & Floors General Information

Introduction

Promat carries a wide range of fire rated ceiling and floor systems

with fire resistance of up to 240 minutes. Generally, PROMATECT®

ceiling and floor systems provide horizontal fire barriers to prevent

vertical spread of fire.

PROMATECT® ceiling and floor systems have been extensively

tested and assessed to provide resistance to fire from above, below

or above and below. They satisfy the integrity and insulation criteria

of BS476: Parts 20, 21, 22 and 23: 1987 and/or AS 1530 Part 4. The

flooring systems not only meet the integrity and insulation criteria

but also meet the loadbearing capacity (structural adequacy) criteria

of British and Australian national standards.

The system design depends on performance requirements but in

overall terms, PROMATECT® ceiling and floor systems can be

divided into the following categories.

1. Self-supporting Membrane Ceilings

These are normally non-loadbearing and, depending on the type of

construction, are used to provide protection from fire attack from

below and/or above. Ceiling panels are fixed into a steel or timber

framing system spanning and supported between two walls.

Self-supporting membrane ceilings should normally be tested or

assessed in accordance with BS476: Part 22 and/or AS1530:

Part 4 to satisfy the failure criteria of integrity and insulation.

These ceiling systems allow for the protection to or from services

contained within the ceiling void. They will also provide protection

to steel beams that are required to meet the criteria of BS476:

Part 23 where exposure to fire is from below.

2. Suspended Membrane Ceilings

These are normally non-loadbearing and are used to provide

protection from fire attack from below. The ceilings generally

incorporate steel grid systems suspended from a structure.

Suspended membrane ceilings should normally be tested or

assessed in accordance with BS476: Part 22 and/or AS1530:

Part 4 to satisfy the failure criteria of integrity and insulation.

These ceiling systems allow for the protection to or from services

contained within the ceiling void. They will also provide protection

to steel beams that are required to meet the criteria of BS476:

Part 23 where exposure to fire is from below.

3. Loadbearing Floor Systems

The flooring can be of timber or chipboard floorboards supported

by either timber joists or steel joists system. PROMATECT® boards

can be directly fixed onto these joists or fixed to a suspended

exposed or concealed metal grid system.

This type of ceiling should normally be tested or assessed in

accordance with BS476: Part 21 and/or AS1530: Part 4 and is

required to satisfy the three failure criteria of loadbearing capacity

(structural adequacy), integrity and insulation.

4. Suspended Ceiling Protection To Steel Beams

This type of ceiling is used mainly for protection of steel beams

supporting a loadbearing concrete floor slab and should be tested

or assessed to BS476: Part 23 and AS1530: Part 4. PROMATECT®

boards are fixed to a metal exposed or concealed grid system

suspended from the structure above.

Advantages

PROMATECT® ceiling and floor systems require less material to

achieve similar fire resistant levels when compared to the industry

average. This can lead to more simplified construction methods

than the standard equivalent. Use of PROMATECT® therefore helps

to increase productivity and reduce overall installation costs.

PROMATECT® ceiling and floor systems have been developed by

Promat International to satisfy standard requirements for internal

applications. Benefits include:

Time & Cost Effectiveness

Simple construction methods reduce installation cost and time

compared to traditional systems.

Lightweight

Lighter loads on structures compared to industry average systems

for equivalent fire rating.

Thermal Resistance

Excellent thermal resistance performance.

Design Flexibility

Lighter weight allows increased ceiling span, reduced support

structure sizes and/or reduced system thickness.


Tested and assessed to ISO140-3 1995 and ISO717-1 1996 to meet

the needs of the industry. Please refer to pages 41 and 42 for details.

Board Fixing

Longitudinal board joints must coincide with framing members.

If the boards are in one layer, the transverse joints must be

backed with fillet strips made of PROMATECT® boards or timber

noggings for traditional timber joist construction. For boards

laminated in two layers, the joints must be staggered by at

least 500mm.

PROMATECT® boards may be fixed to the steel members using

No.8 “Bugle” head self-drilling and self-tapping screws. No.8

woodscrews shall be used to fix boards to timber frame. For boards

laminated in two layers, the outer layer boards may be stitched to

the preceding layer with No.10 laminating screws.

Minimum edge distance to fasteners and the maximum spacing

between screws must be maintained. Please refer to system detail

for screw spacing requirements.

65



The following are some of the factors which should be considered

when determining the correct specification to ensure a ceiling or a

floor system provides the required design performance under both

fire and ambient conditions. Further advice is readily available from

a local Promat office.

1. Supporting Structure Design

The design of the framing system should be adequate for the

design loads of the ceiling and floor. PROMATECT® systems have

been designed for timber or steel framing as described in the

system specification.

For timber framing system used in loadbearing floor application, it

must be designed in accordance with BS5268, AS1720.1 and/or

AS1684. The width, the depth and the spacing of the joists have to

be carefully specified to ensure that the timber floor will serve its

intended fire performance.

For steel framed ceiling systems, it is critical to adhere to the

dimension of the steel sections, the grid spacing, the suspension

members (if any) and the fastening methods employed. Framing

members could change depending on the factors such as ceiling

span, movement and deflection and local regulations.

Larger or more frequent frame sections can often improve the

fire and structural performance. The framing for the ceiling

systems must be securely fixed back to a substrate that has an

equal or greater fire performance than the ceiling. All fixings must

be non-combustible and must be similar to those listed in the

approval documents.

2. Non Loadbearing Ceilings

Non loadbearing PROMATECT® ceiling systems can be generally

divided into steel frame suspended ceiling and self-supporting

membrane ceiling. The steel framing as noted in the system

specification is appropriate for the given span. Larger dimension of

steel sections or more frequent spacing will be required for a ceiling

span larger than specified.

At wall connections, mechanical joints are required and these joints

must be carefully designed so that they accommodate the required

expansion of steel at elevated temperature.

Non-loadbearing ceilings in this handbook are not trafficable.

Trafficable ceilings for maintenance purposes can be designed.

Further advice on such designs can be obtained from the Promat


3. Loadbearing Ceilings

There are two types of PROMATECT® loadbearing floor systems

available. One is comprised of timber joists while the other is of

steel joists. Flooring material, timber type, thickness and jointing are

all critical. Timber framing shall be of solid timber and must be

designed in accordance with BS5268, AS1720.1 and/or AS1684

whereas for steel framing, the members should be designed in

accordance with BS5950 and/or AS4600.

4. Acoustics

Ceiling and floor systems have been developed to also meet

specific acoustic requirements. These include ratings for sound

transmission, sound impact and sound absorption. Please refer to

pages 41 and 42 for further information.

5. Movement Joint

Movement stress from dimensional changes due to varying

temperature or moisture conditions can cause cracking and

other symptoms of distress in ceiling linings.

Other external forces such as impact or vibration can directly affect

structural movement of ceilings. This movement can be controlled

through a variety of design techniques such as introducing

perimeter relief and slip connections to reduce the transfer of stress

from the structure to other building sub-elements and/or through

the use of expansion joints, control joints and construction joints.

Expansion joints are needed when a ceiling abuts a rigid mass.

Where ceiling dimensions exceed 10m in either direction, a control

joint should be used, (see page 92). Control joints should also be

located to intersect column penetrations, light fixtures and air

diffusers. The introduction of a control joint into a fire-rated system

is essential when an opening for flame and temperature

transmission is created. This and similar openings have to be

properly treated with approved Promat fire-stopping material.

6. Caulking & Service Penetrations

To maintain the fire performance and, where applicable, the

acoustic performance of the ceiling system, perimeter and other

gaps must be appropriately filled with suitable caulking material.

PROMASEAL® AN Acrylic Sealant or other tested fire and acoustic

rated material of equivalent or better performance must be used.

Care needs to be taken in detailing a suitable fire-stopping system

around any penetration of the ceiling by services to ensure:

a) the fire-stopping material remains in situ,

b) fire and smoke do not penetrate the floor cavity

which ultimately will lead to,

c) premature collapse of the joists and/or penetration of

fire and smoke through the timber flooring.

Allowance should be made for thermal movement of the services in

both ambient and fire conditions to ensure loads are not applied to

the ceiling assembly. Some examples of service penetrations

include those penetrations by electrical cables, conduits or wires,

plastic and metal pipes, air-conditioning and ventilation ductwork.

Further guidance on the sealing of service penetrations can be

obtained from pages 93 and 94 of this handbook.

7. Light Fittings

Light fittings located within a ceiling cavity should normally be

enclosed in an adequately supported fire protection box to prevent

fire spreading rapidly into the ceiling cavity. Most light fittings will

require ventilation in normal use and this consideration should

certainly be factored into light box design. Please consult Promat

for details.

8. Access Panels & Hatches

Where access into a ceiling void is required, panels and hatches will

need to be installed. Please refer to page 95 or consult Promat

Technical Department for details.

Conclusion

Most building regulations stipulate limitations on the use of fire

protecting suspended ceilings in certain situations. Care should be

therefore taken that the use of a suspended ceiling system is

acceptable to the approval authorities.

Components Selection

In order to maintain the fire and acoustic performance of

PROMATECT® ceiling systems, the type of profile used for

framing is important. Construction of the PROMATECT® fire rated

steel framed ceilings can be achieved using standard steel section

components. Steel framing may be C or ‘I’ sections, furring

channels, top hats, trusses or similar members which in all cases

should be designed in accordance with BS5950, AS4600 and/or

equivalent standard.

The profiles described in the system specification should be

adhered to at all times. However, the profiles may be amended

as long as they possess comparable performances to the

specified profiles.

Perimeter Tracks & Steel Joists

For Self-supporting Ceilings

This system is the most appropriate especially in situations where it

is difficult to install a suspended ceiling and/or within narrow rooms

or corridors. No hangers are required for this system, producing

shorter installation times and provision of a completely free cavity

for the accommodation of ductwork and services.

For Australia, suitable framing profiles can be obtained from

Rondo Building Services who provide comprehensive

documentation for ceiling framing systems.

The framing system generally consists of a perimeter track profile

and steel joists. During the design stage, choosing the right depth

of the profile takes into account the maximum allowable span. The

main function of the perimeter tracks is to provide friction joints that

hold the joists in position until the PROMATECT® board is fitted.

They also provide allowance for movement of building structure

under ambient conditions. Under fire conditions these tracks allow

for the steel joists to expand to minimise deflection of the ceiling

construction that may cause excessive cracking and then

delamination of the lining boards. This type of joint is suitable for

ceiling membrane systems of up to 3000mm span. Track sections

should be fixed to the supporting structure using suitable masonry

anchors at maximum 500mm intervals. Fixings should be located

not more than 100mm from either end of the track section.

For membrane ceilings with a span of more than 3000mm,

mounting brackets are required at both ends of the steel joists. The

mounting brackets will be attached to the wall, at the same time,

and shall be designed to allow for expansion of the steel joists.

Steel Framing System For Suspended Ceiling

This system is the most appropriate for the installation of large

area suspended ceilings. The steel structure of the suspended

ceiling is composed of a grid of C-profiles and accessories, made

of galvanised steel. The standard length of the C-profile is either 3m

or 6m.

The 1st layer of PROMATECT® 100 boards are fixed to the timber framework using either galvanised clout nails or woodscrews of 50mm

long at nominal 150mm centres, and a minimum of 12mm from the board edge. The second layer of PROMATECT® 100 boards is then lined

against the first layer and fixed to the timber framework with 50mm long nails or screws in a similar manner.

Tests & Standards

The complete system along with material and framing is tested in accordance with the criteria of BS476: Part 21 or AS1530: Part 4.

Mezzanine Floor: P100 12.60 / P100 12.12


The following are standard architectural specifications for ceiling – mezzanine floor systems using PROMATECT® 100. The designer must

determine the suitability of the design to the application and requirements before undertaking or constructing any works relating to the

specifications and where in doubt obtain the advice of a suitably qualified engineer.

Fire Attack From Below / LOADBEARING

60/120* minutes fire rating, loadbearing capacity, integrity and insulation in accordance with the criteria of AS1530: Part 4.


Care should be taken that any structural element by which the mezzanine floor system is supported, e.g. steel framing etc, has fire

resistance of at least 60/120* minutes and is capable of supporting the ceiling system for the required duration.

Lining Boards

One/two* layers of 20mm thick PROMATECT® 100 matrix engineered mineral boards as manufactured by Promat International (Asia Pacific)

Ltd. All longitudinal joints to coincide with steel framing. All joints between adjacent layers are to be staggered by 600mm. Standard board

dimensions 1200mm x 2500mm x 20mm.

Fixing

Systems in AustraliaFAQ’s and Promat systems in Australia __________________ 97

FAQ’s and Promat Systems in Australia

Q1. Is PROMATECT® 100 cheaper than the conventional

plasterboard systems?

A. Overall system costs must be treated as that, a SYSTEM

COST. This not only includes materials, but also the labour to

install them. With the PROMATECT® 100 system, labour rates

can be cut by up to 40% and more importantly, the project

can be completed much quicker before moving on to another

profitable project.

Q2. How quick can I get PROMATECT® 100?

A. Immediately. We have stock in every state of Australia and

can provide you with the material you require on short notice.

We understand the needs of today’s contractor and will

always strive to meet these expectations. Promat Australia

has a proud history of a high level of service which we always

strive to maintain.

Q3. What technical support can you provide?

A. Our trained and experienced sales staff can provide

certification as well as helpful advice on construction methods

and other aspects of our system. Our systems are fully

designed for the Australian market and are fully compliant to

Australian Standards. Therefore PROMATECT® 100 should be

the board of choice for your fire rated barriers.

Q4. What kind of finish will I get with the PROMATECT® 100

system?

A. The finish will be as good as or better than plasterboard and

is finished using the same techniques you will already be

familiar with.

Q5. Do we need any mineral wool infills?

A. No.

Q6. How come only one layer is needed on each side when

plasterboard needs two or three?

A. PROMATECT® 100 is a very different board to plasterboard

and has superior performance as it is a dedicated fire

resistance board and not a hybrid version of non fire rated

combustible material.

Q7. Is it cost competitive to gypsum board alternatives?

A. It is a one layer system either side of steel stud providing up

to 120 minute protection. Competitor systems are required to

use two layers either side. Labour rates are therefore cut in

half making PROMATECT® 100 a competitive alternative.

Q8. What surface finish am I likely to achieve if

PROMATECT® 100 is used?

A. You will have a finish that is extremely close if not better than

gypsum. The PROMATECT® 100 comes with rebated edges,

that allows it to be set. PROMATECT® 100 can be painted

and used as a finished surface.
