RAAFT JOISTSRigid aluminium joists available in 30mm, 50mm and 80mm heights to be used separately or in combination to suit your design requirements.

The joists provide robust spans between supports, significantly reducing the number of pedestals required, increasing the speed of installation and offer greater design freedom for decking choice and tile layouts.All joists provide the ideal platform for our Farrino porcelain decking. Joists are manufactured from aluminium alloy 6063A, which is a high-performance alloy with a high natural resistance to corrosive conditions in normal environments.

W H Y U S E J O I S T S Y S T E M S ? The main benefits of using joists incorporated with pedestals are numerous and we believe pedestal only installations will become a thing of the past. Aluminium joists permit the construction of external floors to harmonise with the quality level of the building as a whole. Kinley’s aluminium joists are assured due to a high grade of aluminium used with a lifetime of 50 years plus.

The aluminium joists themselves are non-combustible. The Building Regulations as set out in Approved Document B (Fire Safety) state that in roof terrace applications gaskets and seals are NOT included in the Class A requirement, it only applies to structural components.

This overdue element to the terrace environment brings with them massively increased stability, a more flexible substructure and a faster and easier installation.

Not only do all the different types of paving layouts become a lot simpler that were previously either very difficult or impossible it also makes it easy to be more creative in paving layout design.

Bridging over gulleys, access points and fixed services becomes easy as the pedestals can move along the joists to suit the base they are being laid on.

An ‘A’ rating means they have met EN ISO 1182 and EN ISO 1716 standards – these are classified as non-combustible materials. An ‘F’ on the other hand means they have failed to meet EN ISO 11925-2 and will be labelled easily flammable. To distinguish between the classes, a subscript of ‘fl’ is added for flooring and ‘L’ for linear pipe.

The other elements evaluated are smoke and burning droplets rating. Smoke results range from little or no smoke generation (s1), to medium generation (s2), and finally, heavy smoke generation (s3). A burning droplets rating measures whether droplets form within 600 seconds (d0), whether droplets form within 600 seconds but do not burn for more than 10 seconds (d1), or if neither scenario occurs (d2).

F I R E T E S T I N G M E A S U R E SThere are three primary aspects that are being examined – fire resistance, reaction to fire and structural integrity. Testing the fire resistant (retardant) measures the material’s ability to resist or prevent fire from spreading from area to area. The reaction to fire determines how a material will affect the fire’s development.

B U I L D I N G M A T E R I A L S C L A S S I F I C A T I O N SThe Fire Test to Building Material-Classification (EN 13501 – 1) separates building materials into three classifications: construction, flooring and linear pipe. Within these groups, materials are assigned classes from A to F.

DESIGN CONSIDERATIONS: NON-COMBUSTIBILITYWhen creating inspiring outdoor spaces, designing the aesthetics, i.e. colour, texture, shapes, balance, is as important as ensuring that the space is safe and functional. Specifying the right materials that have been thoroughly tested could help prevent injury or death. Being aware of the fire ratings for the materials is crucial. Below is a brief insight into the regulatory fire ratings for building materials.


P O S T - H A C K I T T R E V I E WThe Commission Decision (96/603/EC) sets out that products manufactured from the listed non-combustible materials are considered as Class A and these include porcelain, aluminuium and steel.

The Building Regulations Approved Document B for Fire Safety sets out, under Requirement B4 Regulation 7, that the external walls and roof of the building shall adequately resist the spread of fire using materials classified as Class A1 or A2 but this does NOT apply to seals, gaskets, fixings and sealants.

In order to assign this R rating, a ramp is covered with the flooring material that is to be tested. The ramp angle increases in degrees until the tester, who is either barefoot or wearing a predetermined shoe type, slips. The test is then repeated on dry floors, wet flooring and contaminated floor surfaces. The results of the tests performed are averaged and the floor material is given an R rating.

P E N D U L U M T E S TThis method is used for measuring the slip/skid resistance of a road and airfield surface. This test is designed to mimic the point at which most slips occur – a pedestrian heel strike. This allows for the measurement of the dynamic coefficient of friction (CoF) and the aim is to be have a result as close to 1.0 as possible. Measurement of the CoF may

differ based on conditions so it’s imperative the right method is used consistently during the trial. The PTV (Pendulum Test Value) is assigned based on the outcome of this experiment.

The PTV equates to an approximate accident risk and ranges from high (0-24) to moderate (25-35) and finally to low (36+). In real terms, a result of 36 means the probability of slipping is 1 in 1 million, however at 24, every 20th person might slip.

Effectively, there are two critical details to understand about anti-slip tiles: the measurement of the coefficient of friction and the role that slip resistance plays when it comes to avoiding and reducing risk.

pools and wet rooms. The test provides a good indication of wet slip resistance.

ABC classifications are given and is based on the angle at which a slip occurs while gradually increasing the incline. The classification ranges from A (12-17° indicative of high moderate risk) to B (18-23° which indicates moderate/low risk) and C (24° and higher indicating low risk).

R A M P T E S TWhile not all floor tiles will have a rating assigned to them, if they are labelled as anti-slip then they will have an R (ramp test) rating – the equivalent of its likelihood to prevent slips on a flat surface. R ratings vary from R9, which are not tested but meet minimum standards, to R13, the highest slip resistance attainable.


• The ASTM 1028 American test method • The P-17 French test method • The BCR Tortus test • DIN 51130 / 51097: the German test method • Pendulum Test

D I N S T A N D A R D SThe accepted standard that designers and architects abide by in order to ensure they comply with building regulations and mitigate any potential injury claims is called DIN - ‘Deutsches Institut für Normung’ or German Institute of Standardisation.

As a rule, for sloped surfaces, most experts recommend the use of R12 at a minimum, with R13 being preferable. A slope as little as 5° needs a minimum Pendulum Test Value (formerly referred to as Slip Resistance Value) of 45.

It has been calculated that the annual cost of slip and trip injuries to society could be well over £750 million.

Wherever external flooring is used, the onus falls on the specifier to choose an appropriate finish in terms of performance and design. There is also a duty of care to provide solutions to potential problem areas where function has to take precedence over form and safety issues override cost.

There are various test methods used to determine a tile’s “slip resistance”, but to date no method has been universally accepted by either British or European standards.

Among the various methods used are the following:

DESIGN CONSIDERATIONS: SLIP RESISTANCEThe specifier’s duty of care – How to define anti-slip? A material with the appropriate performance characteristics to overcome the problem of people falling over in specific environments. More and more importance is placed on designing-out the risk of slipping on external floor coverings such as terracing in commercial applications.

S T A N D A R D D I N 5 1 1 3 0 : 2 0 0 4This classification is used for footwear traffic and uses heavily-cleated EN:ISO 20345 safety boots with motor oil contamination during the evaluation. The following aspects have all been used in the UK as part of the appraisal:

• testing of floor coverings • determination of the anti-slip properties • workrooms and fields of activities with slip danger • walking method • the ramp test.

S T A N D A R D D I N 5 1 0 9 7 : 1 9 9 2This standard tests the slip resistance of flooring in barefoot conditions using soapy water as a contaminant. The tests are geared toward areas that are generally only accessible without shoes, like swimming

DESIGN CONSIDERATIONS: WIND UPLIFT

It is therefore critical that a roofing system is designed to withstand the wind loadings that are likely to impact on the roof during its service life.

BS EN 1991-1-4: 2005 + A1:2010 Eurocode 1, 'Actions on structures. General actions. Wind actions' defines the methodology to be used for the calculation of wind loads and their application.

When installed in accordance with the manufacturer's recommendations, the Preventa clip fixing systems (see page 13) create a dynamically stable terrace system, which will have enough weight to avoid the risk of wind uplift in most cases. In areas of severe exposure or where the specifier needs to be extra cautious, the addition of ballast around the pedestal bases will more than suffice.


Podium courtyards can have an extensive amount of space available and it may be necessary to include some kind of void filler to reduce the construction depth. However, these zones can also provide valuable opportunity for water attenuation zones to assist with balancing drainage flow from the buildings and contribute to overalls Sustainable Urban Drainage (SUDs) requirements.

D R A I N A G ETaking into account the drainage provision of the roof terrace is also key. We’ve found in the past that drainage outlets can often clash with the positioning of pedestal supports or where foundations for planters are required. Identifying these early in the design process can save complications and frustration at construction stage.

It is also important to think about any special requirements for the terrace – for example, what plants might be needed, or the different surfaces that will be incorporated into the design. These can also affect the water drainage system required.

A C C E S S I B I L I T YConsiderations for the design will include the typical age range of people using it and whether the space will need disabled access, or indeed will be used by children. Work space, for example, will have a completely different set of criteria to a recreational or private area. Disabled access will need more thought around navigating the site, access points and ramps, as well as having wider footpaths. School play areas will require different finishes and additional safety features.

R O O F S T R U C T U R EA key challenge that we face on the roof terrace environment is having sufficient build up depth from the waterproofing to the finished floor level to allow for the construction sub-structure and pedestal system. Inverted roof systems (where the insulation is installed on top of the roofing membrane) can further limit the amount of available space so this is something that needs to be identified and established at an early stage. It is also important not to forget to take the door threshold levels into consideration.

OTHER DESIGN CONSIDERATIONS

R O O F L O A D I N G SWhen designing a roof terrace, there is the added complication of what is underneath.

If the roof itself has not been designed to take a sufficient load bearing capacity, it will need reinforcing. This is normally the key responsibility of the architect or structural engineer for the project. It is particularly important on refurbishments and when retro fitting roof terraces to existing buildings. Remember that soil is heavy, especially when wet, so be sure to do the calculations to ensure the roof structure can support your design!

All roofs are subjected to the effects of wind uplift as the wind moves across them. The affects of this will depend upon a number of factors including their location, height, size, roof shape and relationship to the surrounding area.

INSTALLATION AND MAINTENANCE


The roof surface area must be completely stable and include suitable provision for drainage.

Kinley recommends installing the total Preventa terrace system build-up in smaller, manageable areas, rather than setting out pedestals and joists across the whole roof area.

Check that the correct pedestal height has been specified and also that the whole system including the porcelain decking will finish level with the required floor height.

Rather than laying out the pedestals it is quicker and easier to click each joist into the pedestals. Please allow five pedestals per 2.4m joist length, starting 100mm in. At the perimeter of the decking area, when using full joist lengths, there will be a maximum 100mm overhang at both ends.

If required, joists can be easily cut on site using a circular saw.

Place the made-up support system at maximum 400mm centres, i.e. each full length 1.2m long porcelain plank will be supported by four joists. At decking end laps, do not end a plank on a joist, but place two support systems side by side

Locate and screw fix in the starter/end clip at the end of the joist where the decking begins.

Access clips should be used where periodical access is required, e.g. for utilities sited below the terrace system. These can be twisted into the ‘locked ‘position by a normal screwdriver. If access is required the process is reversed, enabling the decking plank to be removed.

Locate the decking planks, and apply and twist the mounting clips to ‘lock’ the decking into position. Abut the next decking plank to the mounting clip. This provides a natural gap of 5mm between planks.

Ensure two joists are laid where two boards meet as shown above. The maximum distance between these joists should not exceed 60mm.

At the end of the decking run, boards may be cut to suit using wood tools, if required. In this case, use adhesive to fix last board.

C O N T R A C T O R A C C E S SConsider the logistics. It sounds simple enough, but it is easy to forget something that could ultimately hold up the construction, or stop it altogether.

One key consideration is to ensure that you can get what you are designing into the space, bearing in mind that a lot of construction for the building will have already taken place. It is quite likely that the roof terrace will be installed at the end of the project. For example, we have seen projects where contractors reach the 9th floor but have no crane on site, making it very challenging (and costly!) to get supplies to the roof space. Keeping this question in mind through the design and construction scheduling phases of the project can save a lot of time, cost and stress later on.

If you are designing or constructing a roof terrace, speak to one of our technical specialists who can help you making sure you have taken all logistics into consideration, and help you choose the right products to create the desired finish.

If wind uplift is a potential issue, use ballast on the pedestals.

ALWAYS CHALLENGING THE STATUS QUO

OTHER PRODUCTS


A B O U T K I N L E YWe don’t just want to improve how things are done. We want to solve new challenges. By turning a problem on its head and exploring new, interesting and innovative ways to fix it, we continue to move forward and stay at the forefront of innovation. This is the exact reason why we created the Preventa system.

We help landscape developers, architects, designers and specifiers to push the boundaries of what’s possible for urban landscapes. Through innovative and superior quality products that work individually or as a complete system, we want to make inspiring, contemporary, functional and reliable places for people to enjoy.

Our team is a little bit obsessed with delivering quality products, going that extra mile for customers and making every process make sense.

We ensure the integrity and superior quality of all our products through our own quality management system.

We prove quality in a number of ways, including

• product testing – once a product has passed our own vigorous testing, we send it to a professional laboratory for seal of approval

• providing samples to clients – see the quality of a product for yourself and try it on-site before buying

Kinley products are used in commercial landscape projects of all shapes and sizes, across the world. Our landscape edging, composite decking, bespoke planters, support structures and porcelain tiles for terrace systems are all practical products that turn ordinary outdoor spaces into innovative, imaginative and enjoyable environments.
