If you’re a specifier looking for decking that looks like timber but that needs to achieve a Class A fire rating, either for a high-rise building’s balcony or terrace, then you might be struggling for choice.
Building regulations in the UK mandate that only non-combustible materials are to be used on residential buildings above 18m. As this includes balconies and other specified attachments, external flooring must therefore achieve a fire rating for Class A1 or A2.
A1 materials are completely non-combustible whereas A2 materials have limited combustibility. Both types are considered non-combustible and are permitted on external applications on buildings of any height.
Although you might not be able to specify timber or composite decking, there is now another option available to you other than aluminium decking.
