An unprotected standard air-brick could allow over 5,000 litres of water per hour to enter your property.

Stop water ingress via ordinary air-bricks with automatic passive solutions.


Flood Angel Anti-flood Airbrick

Available in 5 standard colours, the Flood Angel Anti-flood Airbrick is the world's first BSI Kitemark certified airbrick to protect against flooding. (PAS 1188-1:2014)

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.

  • Can be retro fitted or used in new build construction
  • Made from recycled polypropylene
  • Standard colours to match exterior brickwork: terracotta, engineering blue, black, white, buff
