Disclaimer:

1) The installation of Rytons A1 Fire-rated Air Bricks alone will not satisfy the requirements of high-rise buildings i.e. those 18m high or more complying with 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.
2) We do not recommend purchasing Rytons A1 Fire-rated Air Bricks separate from Rytons A1 Fire-rated Ducting.  All components are made by hand and have a size tolerance of +/- 5%.  Therefore, we can only guarantee compatibility between the air brick and the ducting if they are fabricated together and supplied as a full kit.
