Cavity Liners & Air Bricks
More information about Cavity Liners & Air Bricks
What are air bricks and what types do we have available?
Air bricks are used in construction to allow proper ventilation and airflow for homes that have suspended floors, such as basements and crawl spaces.
Specially designed to improve the air circulation through walls and subfloors, air bricks have perforated or latticed surfaces to allow air in while keeping insects, birds or rodents out. Using air bricks is especially important in areas of high humidity or where controlling moisture is a top concern. An airbrick vent not only helps to regulate airflow, but temperature and humidity too, helping to reduce damp, condensation, mould and rot.
We’ve got a good variety of clay air brick vents, also known as brick weep vents or ventilation bricks, available to browse from. Depending on the aesthetics of your customer’s home, you can choose from terracotta air bricks, buff air bricks and more to blend seamlessly into the outer walls.
The Cavibrick Air Brick is a high-performance cavity wall air brick with a louvred design and a built-in air brick cover and insect screening, helping to provide better ventilation and doubling as a barrier for insects. The telescopic design of the Cranked Telescopic Air Vent allows the airbrick to run vertically through the brick structure, allowing a clear airflow passage to suspended floors.
Our range of cavity liners
Cavity liners are used alongside air bricks to provide a bridging duct across cavity walls and allow much needed ventilation, preventing the build-up of gas or damp.
We’ve got some terracotta cavity liners available to purchase that are suitable for both new-builds and home refurbishments, including our 215 x 215mm Cavity Liner and the smaller 215 x 65mm Cavity Liner depending on the size of the air brick.

FAQs
Air bricks, also known as air vents or vent bricks, are bricks that contain holes and are designed to allow air to circulate in buildings that have suspended floors to improve ventilation.
Yes – cavity walls need ventilation to prevent the build-up of moisture which leads to condensation and dampness. Air bricks will provide the cavity walls with proper airflow and help with the structural integrity of the wall.
Yes – air bricks are designed to allow proper airflow which reduces the amount of moisture in walls and subfloors. They help to prevent damp, condensation, mould and rot.
It is possible for mice, other rodents and insects to get in through the holes in ground-level air bricks. To combat this, place a wire mesh over the front of the air brick (never block the holes fully).
