Anti Flood Air Brick Buff

Fernco Anti-Flood Air Brick in Buff is a direct replacement for standard clay or plastic air bricks, combining essential sub-floor ventilation with automatic flood protection. A self-activating float valve seals when water rises and reopens as it recedes, delivering hands-free operation for new build and retrofit applications, including listed properties. UV-stable construction and a Buff finish help it blend with lighter brickwork while supporting long-term durability.
