A2fl-s1 / A2, s1- d0 Fire Rated Decking
It is now a legal requirement for all materials in the external envelope of a building, over 18m in height, to be non-combustible. The resulting implications for Housing Associations and Local Authorities has been wide reaching with a call for the refurbishment of housing stocks across the UK where combustible materials are present in building envelopes.
Adek is a non-combustible decking system that is A2fl-S1 & A2-s1,d0 fire rated. At the forefront of Adek’s development was the need to create a non-combustible decking product flexible enough for the replacement of existing combustible decking products which is why the team created a 147mm board within its range.
All our Adek systems are fully compliant with the latest building regulations and have been designed in accordance with BS 8579:2020 – the design code for balconies.

Adek's RIBA Approved CPD For Fire Rated Decking
Adek is committed to helping architects & specifiers alike, through CPD learning, in the use of aluminium decking for balconies, walkways and terraces. There is now a plethora of legislation, design guidance and fire testing surrounding the topic of non-combustible decking which can be challenging to review.
This is why we have developed a RIBA approved CPD: “A Specifiers Guide To Non-Combustible Decking Systems” which provides you with an overview of all the different factors you need to consider when choosing the flooring material for your next project.

Housing Association & Local Authority Resources
Adek have developed a Technical Hub to allow you to browse documentation, drawings and supportive information about our Adek systems all in one place to assist you with the design of your decking project. This includes a full suite of detailed technical datasheets which are available to download.

Adek Systems A2fl-s1 Fire Rated
All Adek profiles have undergone independent third-party testing to BS EN 13501-1: 2018 and have been classified at A2FL-S1 which means that it is non-combustible and that its smoke emissions are weak or absent. This, therefore, means all Adek systems, as a non-combustible decking, are appropriate for use in balconies and roof terraces in buildings over 18m in height.

Yes - All Adek systems are non-combustible and carry a fire rating of A2FL-S1.
Adek products have been developed with the retrofit market in mind. Our Adek boards come in either 20mm or 30mm heights which will cover most project requirements which are replacing wood or composite.
All our boards can be cut onsite to reduce their overall length. Additionally, our 295mm wide span boards in both Comfort Grip and Enhanced Grip, can be ripped length ways onsite to fit a require space. A specially designed Adek support leg is used on the cut edge to finish the decking system.
Yes, our systems are face fixed through an integral channel which is subsequently covered by an easy fit channel cover to conceal the fixings. This means there are no fiddly decking clips required. We also have a wide span 295mm board that enables large decking areas to be covered rapidly.
Both Comfort Grip and Enhanced Grip boards have been tested in accordance with HSE guidelines and are categorised as having low slip potential in both wet and dry conditions. The Enhanced Grip range of boards offers a 19.5% increase in grip resistance (in wet conditions) in comparison to the Comfort Grip due to its low profile raised ridge.
All Adek systems come with a 30 year warranty.
Yes – it is non-combustible.
Yes – the Adek channel profile allows for lifting eye bolts to be used even with the boards already installed. The channel is simply pre-drilled wide enough to allow the lifting eye fixing to pass through unobstructed and then secured to the balcony substructure below. Once the balcony is lifted and installed in its final position, the lifting eyes can be removed and the remaining holes are then concealed by our unique press clipped channel cover
Yes, we have various thicknesses of boards, bearers and pedestals to supply.
Yes, all of our testing and certification is available in our Technical hub on our website.
