Cast iron air bricks are used either externally or internally, built into walls (either brick or stone) to fit flush with the wall surface and secured in place with mortar or plaster.

9" x 3" (225 x 75mm) air bricks are a very popular size as it is the standard size of an old fashioned British house brick. If air flow is important, again the max flow, as the name suggests is a clear winner.

The 9x6 air bricks are twice the size of a standard house brick, therefore allowing a greater free air flow. The 9x9 and 12x9 air bricks are also available to supply larger air flows.
