What does an air brick do?
Air bricks, sometimes called air bricks or air vents, are special bricks containing holes that allow air to enter under the floor of buildings that have suspended floors. Cavity walls also need ventilation to allow airflow that will prevent moisture build up.
Are air bricks necessary?
If your house has timber floors or a beam and block floor you should have airbricks to allow air to circulate underneath the ground floor, this is also known as ventilation. All properties with hollow floors should have air bricks built into the wall to allow a free flowing passage of air.
Do air bricks stop damp?
An airbrick is a special type of brick that contains holes to allow the circulation of ‘fresh’ outside air beneath suspended floors and within cavity walls to prevent moisture building up as a result of cold or damp air ‘sitting’ in voids or empty spaces.
Will an air brick stop mould?
If air lingers and stagnates it can lead to perfect conditions for black spot mould to form. Cleaning air bricks with a bottle brush once a year will greatly improve sub-floor ventilation and reduce the possibility of wood rotting fungal decay like dry rot.
Should air bricks be above or below damp course?
Airbricks can be positioned either above or below the damp proof course (DPC) level, and should ideally be incorporated on all sides of a building, typically at least 75 mm above the ground to prevent water ingress.
Do modern houses have air bricks?
Some modern airbricks are made from plastic which can be more durable and enable a greater rate of airflow. An alternative to airbricks is the use of cast iron grilles, known as air vents.
Where should air bricks be placed?
Can I fill in an air brick?
