Hereof, is it necessary to have air vents in walls?
No worries, But yes you must have some form of ventilation, either trickle vents in the windows, acoustic trickle vents in the walls or a heat recovery system. Unfortunately moisture in the air is common of everyday living and it needs to go somewhere and we need changes of air too.
One may also ask, how many brick vents do I need? How many vents you'll need will depend on the size of the void underneath the floor. As a general rule of thumb, you should place one air brick every one and a half metres to two metres along the wall. For large buildings, install the air bricks placed at one and a half metres and consider using larger air bricks.
Besides, what is the purpose of air bricks?
Airbricks, 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.
Can I block the air bricks in my house?
If the air bricks are blocked or closed this will reduce the ventilation and the risk of serious rot and damp will be increased. Air bricks should never be blocked or closed and it is recommended that all air bricks are inspected and cleaned on an annual basis.
