Anti Flood Air Brick - Buff

Fernco Anti-Flood Air Brick - Buff

Our Fernco Anti-Flood Air Brick in Buff is a simple but effective way to help protect your home from flooding without affecting the ventilation your property needs every day. Finished in a soft buff colour, it blends in naturally with lighter brickwork, making it an ideal choice for modern homes, traditional properties and renovation projects where appearance matters just as much as performance.

At first glance, it looks just like a standard air brick, but inside there's a clever floating valve that's always ready to do its job. During normal conditions, air flows freely beneath suspended floors and through wall cavities, helping to reduce the build-up of damp and condensation. If floodwater starts to rise, the valve automatically lifts into place and seals the opening, helping to stop water from entering your property.

The best part is that there's nothing for you to do. As the floodwater disappears, the valve simply drops back into its normal position, allowing fresh air to circulate once again. There's no need to activate it, reset it or carry out any complicated maintenance, making it a reliable solution that's always working quietly in the background.

Whether you're replacing an old air brick, improving your home's flood protection or specifying products for a new build, the Fernco Buff Anti-Flood Air Brick offers an easy upgrade that could make a real difference when heavy rainfall or flooding occurs.
