The Buffalo Anti-Flood Airbrick is innovatively designed in the same shape as a standard airbrick, and in normal conditions will allow air to flow through and ventilate the space underneath the floor, as intended. Inside the Buffalo Anti-flood Airbrick is an innovative floating seal which automatically closes the vent when flood water approaches. A valve is lifted by the pressure of the water, creating a flood seal in the vent and preventing water from entering the property. The seal will re-open once the water has receded, allowing ventilation to the sub-floor of the building once again. The Buffalo Anti-flood Airbrick is a passive flood protection product, which means no human intervention is required to prevent the property from flooding.
