VV9 Air Brick


9 x 9 Vertical Victorian Slotted Air Brick painted black.

Used more commonly in larger late Victorian and Edwardian properties where a bigger free area of ventilation was required often for supplying combustion air for open fires or boiler air in commercial premises.

Although known as the vertical slotted air brick, it can of course, be turned 90 degrees and installed with the slots running 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 known as a Cavity Horizontal Extension (CAVHEXT9) which 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.

Properties using this air brick include the Royal High School in Bath and Hampton Court Royal Pavillions.

Please note – this air brick is supplied painted black as standard. We can supply bare metal VV9 air bricks at the same price for customers wanting a rust finish or to add their own finish. Please make a note that you require a bare metal finish when placing your order in the additional comments box. For company orders we can supply air bricks in any RAL colour, professionally primed with 3 part epoxy 2 part gloss or matt top coat at an additional cost of £200+vat- please email item number, quantity and RAL number for a proforma for this.
