    "You need air bricks to let air flow under house. To prevent stagnant water, and damp."

    "Airbricks are designed to ventilate cavities/beneath floors etc, there’s no cons really."

    "Air bricks are made of either cement, plastic or metal and are similar in size and shape to a regular house brick; they also have holes in them for ventilation.

    They are primarily used to create an airflow underneath a suspended ground-level timber floor that has a void underneath it.

    Without adequate ventilation, suspended timber floors will experience a build up of condensation in the colder months; this can lead to damp problems, rot, insect infestation and the structural collapse of the floor."

    "Air bricks are used to let air flow underneath the building, to release the build up of gases that emerge from the ground,as these are released all the time,the finest example to see this is when sat by a lake,and you will see bubbles all of a sudden start to appear in the margins,this is caused by gases being released"

    "Air bricks provide ventilation to the underfloor void if you have a suspended floor- could be timber joist or concrete block and beam. Also an air brick will provide a certain amount of trickle ventilation if installed at height, also know as vent brick."

    "Hi , for me there is a few air bricks those for cavity to keep the air flow in the cavity keeping the cavity dry , and the other is a vent going all the way through into the 2walls letting in air flow , plus another called passivise vent which has insulation in between the vent to just let air out or in slowly, to me it’s a waist of time this is to keep damp from forming inside your room or bedroom, if damp is on your ceiling check your insulation in attic is covering your ceiling as black mould will form we call this a cold spot moisture on the ceiling , plus I don’t recommend getting cavity insulation you will have trouble later with damp . Hope this has helped you."

    "They improve ventilation within the walls, avoids mould and gas build up.
    Cons are they can invite pests but unlikely you’ll even notice, finer the gaps the better for pest control"
