VV9 Air Brick Painted

VV9 Air Brick


Slotted 9×9 Air Brick painted black.

A very common air brick used extensively in late Victorian and Edwardian properties for use externally for supplying combustion air for large open fires and vents requiring larger air flows such as kitchens.

Normally fitted with the slots aligning vertically, this air brick can be installed with the slots horizontally.

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 (CAVHEXT9) can be used to transfer air through the wall to an internal grille such as the Heritage 9×9 (item HER9).  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.
