Disclaimer:

• The installation of a Rytons A1 Fire-rated Air Brick alone will not satisfy the requirements of high-rise buildings i.e. those 18m high or more complying to Regulation 7(2) and Approved Document B, and those 11m high or more complying to 2.7 of Building (Scotland) technical handbook 2019, which require all materials forming part of the external wall, or a specified attachment, to be made from non-combustible materials.  For compliant full ducting kit alternatives see Rytons A1 Fire-rated Ventilation Range.

• We do not recommend purchasing the A1 fire-rated air bricks separate to the A1 fire-rated rectangular ducting.  All components are made by hand and have a size tolerance of +/- 5%.  Therefore, we can only guarantee compatibility between the air brick grille and rectangular ducting if they are fabricated together and supplied as a full kit.
