VV3 Air Brick


9 x 3 Slotted Air Brick painted black.

A very common air brick used extensively in late Victorian and Edwardian properties. Unusually, this air brick was fitted both inside and outside properties, often for supplying combustion air for open fires.

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. Using the VV3 on the outside, complete with a Cavity Horizontal Extension (CAVHEXT3) air can be transferred through the wall to an internal grille such as the Daisy Grille (10×4 inch) item 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.
