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.

For larger 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 – please email item number, quantity and RAL number for a proforma cost for this.

This imperial air brick can be used with the METIMP aluminium sleeve and/or duct tape to use with the metric plastic Rytons ducting for cavity wall sleeves and periscope duct which are available separately on this website.

It isn’t possible to install flymesh at the back of this air brick as the mesh will either become dislodged or will block without the ability to clean it. If flies, wasps and bugs are gaining entrance to the property via the vents and are a nuisance the FLY3 cast iron air brick with removable front and integral mesh may be a more suitable alternative. Please note mesh cannot legally be used (UK – current GAS Safe and HETAS regulations apply)  vents where the vents are required to feed a combustion appliance or the room where there is a combustion appliance.
