The Flood Angel® Anti-flood Airbrick is the world’s first BSI Kitemark accredited airbrick to protect against flooding. (PAS 1188-1:2009)
It is the most efficient and effective airbrick replacement on the market. Its superior design is passive and it is self-activated by only one moving part.
Designed to replace a standard airbrick it allows air to freely pass through complying with BS493:1995, but under flood conditions its self-activating gate will automatically shut off.
A removable integral mesh prevents the ingress of insects and debris which may otherwise impinge on the moving part. This unique mesh is imperative to the efficient functioning of the airbrick.
- Fully compliant with the Code for Sustainable Homes

The brick is constructed from durable materials, e.g. recycled polypropylene co-polymer with UV stabilisers against deterioration and silicone sponge. Silicone sponge has been approved by the WRAS (Water Regulations Advisory Service). The Flood Angel® Airbrick has an excellent resistance to ozone, oxidation, ultraviolet light, corona discharge, cosmic radiation, ionising temperature of -20° to 120°.
The product has a minimum geometric open area of 2400mm3 and, therefore, can contribute to meeting the ventilation opening requirements of 1500mm2 run of opposing walls or 500mm per m of floor area for suspended ground floors, whichever is greater, and 500mm per m for wall cavities.
The product, therefore, can be used to meet the relevant requirements of the national Building Regulations and home warranty providers.
