Protect your building with sub floor ventilation

You can use our air brick vents beneath suspended concrete or timber floors to help prevent moisture build up by creating an airflow. This product stops moisture from affecting the structural integrity of your beams and joists to keep you safe.

Both plastic and clay air bricks are incredibly robust and durable. Clay air bricks are the more traditional option because these colour-match well with most external facades.

But we also have a selection of plastic air bricks to suit your needs. We stock plastic floor vents in a range of colours to suit less common house colours, so you’ll be sure to find the right one for you.

We have a wide range of air bricks and vents in different shapes and sizes. Use our duct adaptor to connect your floor vents to existing pipes for easy installation.

Our horizontal extension sleeves are ideal for fitting floor vents through cavity walls. These extenders also mean you can safely add sub floor ventilation through thicker exterior walls without sacrificing the integrity of the building.

Or, try our telescopic floor vents to ensure your air bricks are placed at the best height to work efficiently. Using this product gives you a better chance of keeping your air bricks unobstructed, and is ideal for use with different exterior and interior ground levels.
