GypWallTM STAGGERED

GypWall STAGGERED is a lightweight, non-loadbearing

partition system which offers high levels of sound

insulation performance.

Subject to Local Authority approval, GypWall STAGGERED

can be used as the separating walls between residential

units, such as flats and apartments, to meet the

requirements of the national Building Regulations. The

system can also be specified in commercial and industrial

buildings to meet specific standards of sound insulating

performance in situations where space is at a premium.

GypWall STAGGERED consists of a Gyproc ‘I’ Stud

framework in which alternate studs are staggered within

the floor and ceiling channels to provide a degree of

separation from one face of the partition to the other. Two

options are available Gypframe 60I70 ‘I’ Studs staggered

within Gypframe 72mm Floor & Ceiling Channel (the 60/72

series), or Gypframe 92I90 ‘I’ Studs staggered within

Gypframe 148mm Floor & Ceiling Channels (the 92/148

series). Proprietary Gypframe Spacer Clips are used to retain

the studs within the Floor & Ceiling Channels. Isover

Acoustic Roll is included in the cavity and the staggered

stud framework is lined on both sides with Gyproc

SoundBloc.

INSTALLATION

For full installation details, refer to the Installation Guide at www.gypsum.ie

Gypframe Floor & Ceiling Channel is fixed to the floor and

soffit. Gypframe ‘I’ Studs are fitted vertically into the

channel sections and held in place by spacer clips.

Alternate studs are staggered (offset). As the spacer clips

are friction fitted this allows for stud adjustment during

boarding. Gypframe ‘C’ Studs are fixed at abutments.

Isover insulation is fitted between studs and the perimeter

sealed using Gyproc Sealant.

Boards are screw-fixed to alternate offset studs to form the

lining. Horizontal board end joints of face layer boards

should be backed with Gypframe GFS1 Fixing Strap or

Gypframe GFT1 Fixing ‘T’.

PERFORMANCE

EnvironmentalGyproc GypWall STAGGERED staggered stud partition is

unsuitable for use in areas subject to continuously damp or

humid conditions.

Plasterboards are not suitable for use in temperatures

above 49ºC but can be subjected to freezing conditions

without risk of damage.

Fire protection For reaction to fire classifications for Gyproc and Glasrocboards please refer to Section .

Fire resistance The fire resistances given in Table 2 are for imperforate

partitions tested to BS 476: Part 8: 1972 or BS 476: Part 22:

1987 or assessments based on these tests. Partitions were

tested without timber sole plates.

Sound insulationThe Rw ratings given in Table 2 are for imperforate

partitions and have been tested in accordance with

BS EN ISO 140-3: 1995, and rated in accordance with

BS EN ISO 717-1: 1997 or assessments based on these tests.

Airtightness is essential for optimum sound insulation.

While most junctions will be sealed by standard jointing

materials, gaps at the base of the partition and other small

airpaths can be sealed using Gyproc Sealant.

Partition duty – strength and robustnessThe duty ratings given in Table 2 have been calculated in

accordance with BS 5234: Parts 1 & 2: 1992. The rating is a

measure of the ability of the wall to meet the

requirements of four strength and robustness tests: door

slam, soft body impact, hard body impact, and stiffness.

Grades, e.g. ‘Medium Duty’, relate to the level of activity in

adjacent areas and the degree of care likely to be exercised

in them. The requirements are for walls complete with

their surface finishes where these are part of the wall

specification. Other optional tests may also apply.

Using the duty of a particular wall the designer can select a

wall for its area of use (with due consideration for fire,

sound, or thermal requirements).

DESIGN

Refer to section 3.1 - Introduction, for general

considerations.

Maximum heightsThe criteria to determine the recommended maximum

partition heights are based on a limiting deflection of

L/240 at 200Pa, together with criteria within

BS 5234: Parts 1 & 2: 1992. Greater heights can be achieved

under different criteria. Contact the Technical Sales

Department for guidance.

Cavity barriersWhere a cavity barrier is required, a rock mineral wool strip

cut neatly to fit across the cavity forms a suitable closure.

Acoustic performanceThe partition achieves high levels of sound insulation by

virtue of the mechanical separation between the two rows

of studwork. It is important, therefore, that this isolation is

maintained, and that services, fixtures, etc, do not form a

bridge between the two sets of linings.

Fixing floor and ceiling channelsThe channels must be securely fixed to the surrounding

structure at 600mm maximum centres. 148mm Gyproc

Channels must be fixed with two rows of staggered fixings,

each row at 600mm centres, and each fixing 25mm in from

the flange. If necessary, additional provision should be

made to provide positive fixing points.

If the floor is uneven a 38mm thick timber sole plate equal

to the width of the channel should be used. If the concrete

or screeded floor is new, consideration should be given to

the installation of a damp proof membrane between the

floor surface and the channel or sole plate.

Deflection headsPartition head deflection designs may be necessary to

accommodate dead load or live load deflections in the

supporting floor and/or roof construction. This can be in

the form of live loads on intermediate floors creating a

condition, or a simple minus deflection for dead loads on

the structural floors. Deflection heads may also be required

at the underside of roof structures subjected to positive

and negative pressures. Gyproc GypWall STAGGEREDstaggered stud partitions can incorporate head deflection

designs to accommodate supporting structural deflections

with only a slight reduction in sound insulation

performance (1 - 2dB). See Figs 1 and 2.

4.1

Deflection heads (cont’d)Deflection heads, by definition, must be able to move and

therefore, achieving an airtight seal is difficult. Inevitably,

this will have a detrimental effect on the acoustic

performance of any wall which incorporates deflection at

the head.

Service penetrationsPenetrations of fire resistant constructions for services need

careful consideration to ensure that the integrity of the

element is not impaired, and also that the services

themselves do not act as the mechanism of fire spread.

It is important to use only those services and their

installations which have been shown by fire test to be able

to maintain the integrity of the construction.

The inclusion of service penetrations, socket boxes etc in a

separating wall is not recommended as the sound

insulation may be downgraded.

Installation of servicesThe installation of services should be carried out in

accordance with all available standards, guidelines and

recommendations. Cables should be protected by conduit,

or other suitable precautions taken, to prevent abrasion

when they pass through the metal frame.

Switch boxes and socket outlets can be supported on

brackets formed from Gyproc Fixing Channel or cut and

bent channels fixed horizontally between the studs.

Door openingsAny openings will require very careful detailing if the

acoustic performance of the partition is to be maintained.

Specialist heavy acoustic doorsets may require additional

support. Contact the Technical Sales Department

for guidance.

FixturesLightweight fixtures can be made directly to the partition

lining. Medium weight fixtures can be made to Gyproc

Fixing Channel. Heavy fixtures should be made to

independent timber framing which is installed at the frame

erection stage. The timber member should be notched at

the intermediate stud position. Any contact at this point

will downgrade the acoustic performance of the partition.

Control jointsControl joints may be required in the partition to relieve

stresses induced by expansion and contraction of the

structure. The location of the control joints is at the discretion

of the specifier. It is recommended that they coincide with

movement joints within the surrounding structure.

Ceramic tilingCeramic tiles up to 12.5mm thick with a maximum weight

of 32kg/m2 can be applied using thin bed adhesives (usually

3mm thick). Stud centres will normally require closing

down. Refer to section - Ceramic tiling.

Board finishingRefer to section - Finishing Coat Plasters, section

- Jointing, and section - Decorative effects.

EstimatingThe estimated construction time is 2 - 2.5m2 / man hour

(single layer partition) or 1.5 - 2.5m2 / man hour (double

layer partition) ready for finishing.

Gypframe Floor & Ceiling Channels are fixed at the head

and base to achieve the specified wall thickness. Gypframe

‘C’ Studs are fitted vertically to friction-fit within the

channel sections and to abutments, to form the

framework. This allows for adjustment during boarding.

Studs should be fitted to face the same way and extended

by splicing to the specified height. Additional framing is

installed as required to support heavy fixtures. Where

specified, mineral wool is installed into the cavity-formed

frameworks. The frames are braced using Gypframe GAB3

Acoustic Braces or solid braces formed from Gypframe 99

FC 50 Fixing Channel at specified centres. Gyproc Sealant is

applied to the frame perimeters to seal airpaths. Boards are

screw-fixed to framing members to form the lining.

Horizontal board-end joints in face layer boards should be

backed with Gypframe GFS1 Fixing Strap.

Partition duty – strength and robustness

All the wall specifications given in Table 2 achieve a Severe

duty rating calculated in accordance with BS 5234: Parts 1 &

2: 1992. The rating is a measure of the ability of the wall to

meet the requirements of four strength and robustness

tests: door slam, soft body impact, hard body impact, and

stiffness. The Duty grade relates to the level of activity in

adjacent areas and the degree of care likely to be exercised

in them. Severe duty is appropriate where the adjacent

space is intensively used by the public and others with little

incentive to exercise care. It could be prone to vandalism

and abnormally rough use. The requirements are for walls

complete with their surface finishes where these are part of

the wall specification. Other optional tests may also apply.

Refer to section 3.1 Introduction, for general

considerations.


partition heights given in Table 2 are based on limiting

deflections of L/240 and L/125 at 200Pa, together with

criteria within BS 5234: Parts 1 & 2: 1992.

Cross-bracingLaboratory tests were carried out on walls without bracing.

The results, however, are a realistic representation to site

conditions in which Gyproc Fixing Channel cross-braces are

fitted at the recommended 3600mm maximum centres,

provided that appropriate measures are taken on site to

eliminate flanking sound transmission. Test evidence is

provided by British Gypsum report ATR 1299 where site tests

on a large Multiplex cinema wall achieved comparable

performance to the equivalent specification tested in the

laboratory without bracing.

Some acoustic designers prefer the option of a resilient

acoustic brace. The Gyproc GAB3 Acoustic Brace has been

shown by test not to downgrade acoustic performance in

laboratory conditions. As a result of the mechanics of this

brace, however, fixing centres should be reduced from

3600mm to 3300mm, staggered by 1200mm. Maximum

recommended wall heights will be reduced – refer to

Table 2.

Cavity barriersStone mineral wool cut neatly to fit across the cavity will

form a suitable closure.

Service penetrationsPenetrations of fire resistant or sound insulating

constructions for services need careful consideration to

ensure that the performance of the element is not

downgraded, and also that the services themselves do not

act as the mechanism of fire spread or sound transmission.

Deflection headsPerformance details apply to fixed head constructions.

If deflection is required to be accommodated, contact the

Technical Sales Department for suitable detailing.

Deflection heads, by definition, must be able to move and




the head. The approach shown in section 4.1 Gyproc

GypWall STAGGERED could be considered to minimise loss

of performance. In most cases, a suspended ceiling will also

assist in minimising loss of performance.

Fixing floor and ceiling channelsThe channels must be securely fixed with two rows of

staggered fixings (fixings at 600mm maximum centres and

25mm in from the flange in each row). If the floor is

uneven a 38mm thick timber sole plate equal to the width

of the channel should be used. If the concrete or screeded

floor is new, consideration should be given to the

installation of a damp proof membrane between the floor

surface and the channel or sole plate.

PERFORMANCE DESIGN

Refer to section 3.1 Introduction, for general

considerations.

Planning – key factorsThe overall partition width is 70mm, subject to tolerances

on associated materials.


partition heights are based on a limiting deflection of

L/240 at 200Pa, together with criteria within

BS 5234: Parts 1 & 2: 1992. Contact the Technical Sales


SecurityThe excellent mechanical properties of Gyproc MultiBoard,

combined with the stiffness and resilience of the

Security Sheet, make Gyproc GypWall SECURE a formidable

barrier to entry. It has a high resistance to ‘determined

attack’ and vandalism using hand tools, and good

resistance to attack using power tools.

Ad-hoc tests have been carried out at British Gypsum’s

Building Test Centre. A ‘determined attack’ by a team of 4

using hand tools did not achieve through penetration until

approximately 10 minutes.

Where even greater resistance to attack is required, 0.7mm

flat galvanised steel sheet (by others) can be fixed to

Gyproc Security Sheet prior to boarding.

Cavity barriersContinuous steel angles at the head and base provide

horizontal cavity barriers, whilst the ribs in the security

sheet provide a vertical cavity barrier to the passage

of flames.

Head and base fixingGyproc GA4 Angles are fixed to the sub-structure using

suitable proprietary fixings (e.g. Rawl R-SPT Throughbolt)

at 300mm centres.

ServicesWhilst services can be installed, these should be kept to a

minimum. The installation of services should be carried out

in accordance with all available standards, guidelines and

recommendations. Services are easily accommodated

vertically between the ‘ribs’ of the sheeting. Holes can be

formed in the security sheeting to enable services to be

passed horizontally. These should be minimised in order to

maintain structural performance and where possible service

penetrations should be concealed either above suspended

ceiling level or behind an associated lining.

FixturesLightweight fixtures can be made directly into Gyproc

DESIGN

Planning – key factorsThe position of service penetrations such as ducts and fire

dampers should be pre-determined, and their installation

planned into the frame erection stage. All penetrations will

need to be adequately fire-stopped if integrity is to be

maintained.

Maximum heightThe criteria to determine the recommended maximum heights

are based studs at 600mm centres, with a limiting deflection of

L/240 at 200Pa, together with criteria within BS 5234: Parts 1 &

Door openingsThe designer should consider the thickness tolerances of the

partition types in relation to the proposed door frame

detail. A standard door opening is formed by locating

full-height Gypframe 70 S 60 or 92 S 60 ‘C’ Studs each side

of the opening. The head is formed from a section of

Gypframe 72 DC 60 or 94 DC 60 Deep Flange Floor and

Ceiling Channel fixed to the studs on each side. The

opening is then lined with 38mm thick timber cut to the

width of the stud.

To satisfy BS 5234 requirements for heavy duty partitions,

door framing should be specified as shown in

CONSTRUCTION DETAILS, Fig 6. Gypframe 70 S 60 or 92 S 60

‘C’ Studs are located each side of the opening and cloaked

to door height with channel section. These constructions

pass the ‘door slam’ test where, for a given duty, the

deflection of the door frame is measured after a set

number of slams (e.g. for Heavy and Severe Duty partitions,

100 slams of a 60kg door).

Exceptionally heavy doorsets may require additional

provision. Contact the Technical Sales Department if further

guidance is required.






FixturesIn high usage areas, where misuse may be a potential

problem, heavy fixtures such as wall-mounted sanitary ware

should ideally be backed by framing members.

This can be achieved by fixing into the metal studs, or to

additional framing or timber noggings.

● Acoustic stud option for enhanced



● Can achieve up to 60 minutes fire resistance

● Exceeds BS 5234 strength and robustness

requirements for Severe Duty

● Easily accommodates services within

stud cavity

● Can allow for deflection at the head

● Gypframe metal framework will not twist,

warp or rot

● Loads of up to 55kg can be supported

directly from the Gyproc Rigidur board

without the need for additional grounds

Key facts

GypWall EXTREME is an ultimate impact resistant partition

system for use where even ‘severe duty’ will not suffice. The

system provides a lightweight, cost-effective,

non-loadbearing partition suitable for areas subject to

intensive traffic.

Using only a minimum number of components,

GypWall EXTREME consists of Gyproc Rigidur boards screw

fixed to a lightweight Gypframe stud framework. The

durability and impact resistance of the boards is provided

through the unique combination of recycled cellulose fibres

and dense gypsum.

GypWall EXTREME is fully compatible with GypWall robust

and other Gyproc partition systems. In addition, in double

layer board linings, Gyproc Rigidur is specified as the outer

face layer only. Allowing significant savings on both

material and installation cost.

soffit. Gypframe studs are fitted vertically to a friction-fit at

600mm centres within the channel sections, and to

abutments, to form the framework. This allows for

adjustment during boarding.

Gypframe ‘C’ Studs or Gypframe AcouStuds are fitted so as

to all face the same way. Additional framing is installed as

required to support heavy fixtures.

Inner layer

In double layer systems, inner layers of Gyproc

plasterboards should be fixed with 25mm Gyproc Drywall

Screws around the perimeter of the board at 300mm

centres, and at the intermediate stud at 600mm centres.

In single layer systems, Rigidur boards are fixed using

40mm Rigidur Screws at 300mm centres around the

perimeter of the board, and at the intermediate stud

positions, at least 13mm from the edge of the board. When

using Rigidur boards, always fix from the bottom of the

partition upwards, as per best practice.

Outer layer

Rigidur boards are fixed using 40mm Glasroc Rigidur

Screws at 300mm centres around the perimeter of the

board, and at the intermediate stud positions, at least

13mm from the edge of the board.

PERFORMANCE

EnvironmentalGypWall partitions are unsuitable for use in areas subject to

continuously damp or humid conditions.

Plasterboards are not suitable for use in temperatures above

49ºC but can be subjected to freezing conditions without risk

of damage.

Fire resistanceGyproc Rigidur achieves an A1 Euroclass reaction to fire

classification and Class O in accordance with Technical

Guidance Document 13 (Fire).

The fire resistances given in Table 2 and 3 are for

imperforate partitions. Note that the insulation in

detail is required for fire resistance as well as sound

insulation claims.

Sound insulationThe mass and sound insulating qualities of Gyproc Rigidur

enable high acoustic performances to be achieved.

The sound insulation performance of GypWall EXTREME

partitions can be further increased with the inclusion of

Isover Acoustic Roll, or Isover Ultimate Piano Plus in the

cavity (see Table 2 and 3). Airtightness is essential for

optimum sound insulation.

Partition duty – strength and robustnessThe duty ratings given in Table 2 and 3 have been

calculated in accordance with BS 5234: Parts 1 & 2: 1992.

The rating is a measure of the ability of the wall to meet

the requirements of four strength and robustness tests:

door slam, soft body impact, hard body impact, and

stiffness. Grades, e.g. Medium Duty, relate to the level of

activity in adjacent areas and the degree of care likely to be

exercised in them. The requirements are for walls complete

with their surface finishes where these are part of the wall





EXTREME duty The robustness of GypWall EXTREME is higher than most

severe duty criteria set out in BS5234: Part 2: 1992.

Additional structural performance and durability tests

above and beyond Severe Duty have been carried out to

reflect better the actual use in high traffic areas.

These tests include:

• Resistance to Deliberate Attack

Tests carried out included hard body impact to

destruction and a test designed to simulate an adult kicking

the partition.

• Resistance to Accidental Impact

A glancing blow test was developed to represent the

partition being hit at an angle by hospital trolleys etc.

• Resistance to Accidental Abrasion

In schools, hospitals etc abrasion can be caused deliberately

by keys, pens etc and accidentally by chair backs rubbing

against the wall causing scratch marks to appear due to

long term wear and tear. A scratch test and a hardness test

were developed to simulate abrasion.

In all the above tests, the impressive strength and surface

hardness of Gyproc Rigidur and the GypWall EXTREME system

were demonstrated.

DESIGN

Planning - key factors

Loads of up to 55kg can be hung directly from Gyproc

Rigidur. The position of some services and heavy fixtures

should be pre-determined, and their installation planned

into the frame erection stage. All penetrations will need to

be adequately fire-stopped if integrity is to be maintained.

Electrical

The installation of electrical services should be carried out

in accordance with all relevant legislation, regulations and

guidance. The cut-outs in the studs can be used for routing

electrical and other small services.

Where Gypframe AcouStuds are used, services are routed

through 50mm x 28mm ‘H’ shaped push-outs. Cables should

be protected by conduit, or other suitable precautions

taken to prevent abrasion when they pass through the

metal frame.

Service penetrations

Penetrations of fire resistant constructions for services need



themselves do not act as a mechanism of fire spread.




Wind loading

GypWall partitions are non-loadbearing but can accept a

degree of wind loading, for example when used in

buildings with large or multiple external doors. The

maximum recommended heights in Tables 2 and 3 are

based on a limiting deflection of L/240 at a pressure of

200Pa. Information can be provided on specifications to suit

individual requirements. Contact the Technical Sales


Deflection heads

Deflection heads, by definition, must be able to move and,



performance of any wall which incorporates deflection

at the head. The approach shown in section - GypWall

staggered, could be considered to minimise loss of

performance. In most cases, a suspended ceiling will also


Fixing floor and ceiling channels

Floor and ceiling channels must be securely fixed with a

row of fixings at 600mm maximum centres (148mm

channels require two rows of staggered fittings at 600mm

centres in each row). If the floor is uneven, a 38mm thick

timber sole plate equal to the width of the channel should

be used.

If the concrete or screeded floor is new, consideration

should be given to the installation of a damp proof

membrane between the floor surface and the channel or

sole plate.

Door openings

The designer should consider the thickness tolerances of

the partition types in relation to the proposed door frame

detail. To satisfy BS5234 requirements for heavy and severe

duty, door framing should be specified in accordance with

Figure 5 or 6.

Exceptionally heavy doorsets may require additional

provision. Contact the Technical Sales Department if further

guidance is required.

Control joints

Control joints may be required in the partition to relieve





Fixtures

Due to the inherent strength of Gyproc Rigidur, some

fixtures can be applied directly to the board. Please refer to

the relevant Data Sheet for more information.

Ceramic tilesCeramic tiles up to 12.5mm thick with a maximum weight

Gypframe Floor & Ceiling Channel is suitably fixed at the

head and base. Gypframe ‘C’ Studs or Gypframe ‘I’ Studs

are fitted vertically within the channel sections to form the

framework. Gypframe ‘C’ Studs are fixed at abutments.

Additional framing is installed as required to support

heavy fixtures.

Boards are screw-fixed to framing members to form the

lining, except 6mm Glasroc F multiboard, which is screw-

fixed to Glasroc F firecase linings. Horizontal board joints

should be backed with Gypframe GFS1 Fixing Strap. Stone

mineral wool is fitted into the stud cavity (ensuring joints

are half staggered) and suitably secured prior to boarding

the second side.

Services

Electrical and other services are normally installed after one

side is boarded. Horizontal runs are routed through cut-

outs in the studs.

DESIGN

Planning - key factors

The position of services should be pre-determined and their

installation planned into the frame erection stage.

Cavity fire barriers

12.5mm Gyproc plasterboard, screw-fixed into the web of

perimeter channels or vertical studs, will provide a satisfactory

closure to flame or smoke. Alternatively 15mm Gyproc

FireLine or Glasroc F FIRECASE may be used.

Refer to section 3.9 - Cavity fire barriers.

Services

Penetrations

Penetrations of fire-resistant or sound-insulating constructions

for services need careful consideration to ensure that the

performance of the element is not downgraded and also that

the services themselves do not act as the mechanism of fire

spread or sound transmission.

Electrical

The installation of electrical services should be carried out in

accordance with BS 7671. The cut-outs in the studs can be

used for routing electrical and other small services (see

GypWall CLASSIC Construction details – 1). Switch boxes and

socket outlets can be supported from Gypframe 99 FC 50 or

150 FC 90 Fixing Channels fixed horizontally between studs,

or a high performance socket box detail where higher

acoustic performance is required.

Fixing floor and ceiling channels

Gypframe Floor & Ceiling Channels must be securely fixed with

a row of fixings at 600mm maximum centres. For 94mm

channels and above, two rows of staggered fixings are

required, each row at 600mm centres and each fixing 25mm in

from the flange. If the floor is uneven, a 38mm thick timber

sole plate equal to the width of the channel should be used.

If the concrete or screeded floor is new, consideration should

be given to the installation of a damp-proof membrane

between the floor surface and the channel or sole plate.

Deflection heads

Partition head deflection designs may be necessary to

accommodate deflections in the supporting floor. Deflection

heads may also be required to the underside of roof

structures subjected to positive and negative pressures. See

Construction details – 1 - 2. Refer to section I (iii) – Principles of building acoustics.

OpeningsFireWall is used to divide space into fire compartments and, assuch, openings are generally not required. If openings are tobe specified they must be shown by fire test to maintain thefire performance of the wall.

Fixtures

Lightweight fixtures can be made directly to the partitions.

Medium weight fixtures can be made to Gypframe 99 FC 50

Fixing Channel. Heavyweight fixtures (to BS 5234), such as

wash basins and wall cupboards, can be fixed using Gypframe

150 FC 90 Fixing Channel.

Board finishing

Refer to section - Finishing systems and section -

decorative effects.

Key facts

BlastWall

BlastWall offers resistance to explosive devices, such as car

bombs, and can be specified in areas such as post rooms

and blast refuge areas. The system has been tested and

approved by some Government departments in the UK.

Specifications are determined on an individual basis

following consultation with Gypsum Industries and

specialist blast design consultants as to the performance

requirements. For detailed information on the BlastWall

system, please contact the Gypsum Industries Technical

Sales Department.
