Anti-Flood Airbrick


A standard airbrick left unprotected could allow over 5,000 litres of water per hour to enter a property during a flood.

Available in 2 standard colours, the 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.

Colours available: Black & Terracotta

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.

Inspection and maintenance is made easy with a fully rod-able system and a clear inspection lid. Sewage backflow can cause untold damage resulting in long term consequences and high clean up expenses. This can be prevented using this simple yet effective product.

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 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 2400mm2 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.
