Y3 Air Brick
9 x 3 Victorian Y Pattern Air brick with the choice finishes, bare as standard or painted black (+$10).
Used throughout the UK and extensively in early to late Victorian properties.
Although not a perfect fit, duct tape can be used to adjoin this imperial sized air brick to a metric sized plastic cavity wall duct. This item known as a Cavity Horizontal Extension (CAVHEXT3) can be used to transfer air through the wall to an internal grille such as the Union Jack Vent (UJ3) or the slightly larger Daisy vent (DAY104). Mesh cannot be fitted in this air brick but is more suited to be installed behind the internal grille (and it can be regularly removed for cleaning) were it serves to prevent bugs entering the rooms and reduces draughts, albeit reducing the free air by 1/3rd.
Product specifications can be found in the table below.
Cast Iron Air Bricks
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.
