Product Information

Terracotta clay and cast iron bricks were traditionally used, which is why you see them on older buildings. If your floor is creaking then it may be a sign that there is a problem with the joists, caused by condensation and rot.

The easiest way to attach mesh to air bricks is to drill holes in the surrounding bricks and use plugs, screws and washers to keep it tight.Can be either glued or screwed in place, available in Small (245 x 95mm), Medium (245 x 170mm) or Large (245 x 245mm). You will want to know what size of air bricks to to fit and what models are available when you choose your air brick. Nevertheless, mice can also travel freely from home to home by following the pipework running below the floors and within the walls.

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. It is shaped like a ‘Z’ and works like a periscope – funneling air down below the floorboards, from a hole above the internal floor level, see the images below. I used to keep birds, mice, young ones (but they soon grow), can get through 1" x 1/2" weldmesh, they squash down flat and shimy through.Of course the method we have just described is for older single skin houses, but what if you need to install an airbrick in a cavity wall? Alternatively if you don’t fancy doing it yourself there are many pest control and timber preservation companies in the UK that can certainly do it for you. Traditionally air bricks were made of clay, but latest models are made of plastic, which are less easily broken, and can also allow a greater airflow than the old clay versions. Featuring heavy-duty mesh with 2mm holes, the covers effectively prevent rodents from gaining access.

To allow the air to flow around and through these walls, the brickwork is very often laid in honeycomb bond. Where the ground level has built up above the level of your existing air bricks you will need to either dig away the earth or fit special telescopic air vents to deal with this problem – see fitting air bricks above. If the ground is solid, perhaps tarmac or concrete, they can be placed lower, provided the ground slopes away from the wall.Well of course a cavity wall is thicker and you will need to get through both skins to fit the air vent. In addition, the airflow created by installing air bricks provides ventilation for solid fuel fires and stoves and gas heaters. As a general rule of thumb, you should place one air brick every one and a half metres to two metres along the wall. By improving ventilation, air bricks help reduce humidity and prevent a build-up of moisture that can lead to damp and rot. Available in five colours, this low resistance air brick has been designed to comply with the latest Building Regulations Approved Document F, which requires a ventilation outlet to achieve a minimum of 90% of the cross sectional area of the ductwork.

For large buildings, install the air bricks placed at one and a half metres and consider using larger air bricks.

Adding a conservatory to one wall of a house can result in air bricks on this wall to be blocked by the concrete slab on which the conservatory is built. The hole this time must be much larger, because you need to get the staggered sleeve into the inside of the wall and build in the stagger so the top section is flush with the external face.
