Fly3 Air Brick

From: £85

9 x 3 Fly Screen Air Brick with choice of finishes, bare as standard or painted black (+£10), with the option of adding a Flood Screen (+£10).

Mainly used as an exterior air brick, supplied to the London Olympics 2012 for use in the athletes village it can also be used with cavity wall sleeve item CAVHEXT3 and the daisy interior grille (item DAY104).

The mesh is a copper mesh of 1mm gauge with 1mm x 1mm square holes ideal for preventing ingress of flies, wasps and rodents.

The flood screen is a cork gasket that can be used to replace the mesh when flooding is imminent and likely to occur , it is then removed when danger has passed. It is useful to keep on standby for ground floor installations especially in low lying areas, properties near the coast or rivers or properties in an area with a history of flooding.

Choose a bare metal finish to allow to rust for “industrial look” or installation in red brick properties where the rust wont stain the render or bricks, for light bricks and coloured render choose painted black finish. Customers can also prime and paint bare metal air bricks to their own colours with oil or epoxy paints.

For larger orders we can supply the fronts of these 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  metric plastic Rytons ducting for cavity wall sleeves and periscope duct which are available separately on this website.

Please note mesh cannot legally be used (UK – current GAS Safe and HETAS regulations apply)  on vents where the vents are required to feed a combustion appliance or the room where there is a combustion appliance.
