WIN9 Air Brick


Metric three size Windsor Air Bricks 213 x 200mm with a choice of finishes, bare metal or painted black (+ £30) used almost exclusively in external walls. The WIN9 is made up of three interlocking WIN3 air bricks.

For commercial 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 cost for this.

Often used with cavity wall sleeves this air brick fits the plastic sleeves and is available combined with a cavity wall sleeve (Item CAV9) instead of buying the air bricks and sleeves separately. It isn’t necessary to use METIMP adapter with the Windsor air bricks as they are designed to fit directly into plastic cavity wall sleeve. Being slightly smaller than the imperial 9×9 air brick, the Windsor air brick is ideal for use in modern extensions, were more mortar is required, in narrow courses of brickwork or in any metric brick installation. The WIN9 should fit within three courses of brickwork.

Clients and customers of this product are numerous and include architects and builders across the country. Installations include a wide variety of properties old and new, this and smaller single version are installed in the new HD ready set for every property in ITVs Coronation Street as well as Ilgars manor, Chelmsford and Walmer Castle in Deal. We see an ever increasing number of installations in converted period properties that are reused and extended as public offices or in the private sector as hotels and wedding venues, examples are Stavely Hall in Chesterfield and Rushton Hall Hotel and Spa

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 FLY9 cast iron air brick with removable front and integral mesh, may be a more suitable alternative or consider installing the mesh on the internal vent.  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.

Painted vents use two part epoxy black gloss top coat which is hard wearing but is just a decorative finish, like all painted cast iron products it will require repainting from time to time, especially if situated on an exposed wall. Repainting can be frequent if the grille is positioned in the sunlight, or chipped or exposed to salt air . The gloss paint will dull over time, in exposed conditions it is likely to dull to a satin sheen fairly quickly. Regardless of the paint finish the cast iron grille will last for many decades with or without painting.
