Plastic Airbrick 9 x 3 (Beige, Black or Terracotta)


SKU: PlasticBeige-old Categories: ,

Product Description

Airbricks are small, perforated bricks or blocks designed to allow the free flow of air into and out of buildings, particularly in structures with suspended floors or cavity walls. They play a crucial role in ventilation and moisture control within a building.

  • Supplied in single units approx 225 x 75mm which clip together to increase size and airflow.
  • 2 units can do 225 x 150, or three give 225 x 225.


Here’s a breakdown of their functions:

  1. Ventilation: Airbricks facilitate the exchange of air between the inside and outside of a building. Proper ventilation is essential for maintaining a healthy indoor environment by preventing the buildup of stale air, odors, and pollutants.
  2. Subfloor Ventilation: In buildings with suspended floors, airbricks are commonly placed along the exterior walls at ground level. They allow air to circulate underneath the floor, preventing dampness and reducing the risk of mold or rot. This is particularly important in older buildings with solid floors, as it helps to address issues related to moisture.
  3. Cavity Wall Ventilation: In structures with cavity walls (walls with an outer and inner layer separated by a gap or cavity), airbricks are often installed to provide ventilation within the cavity. This helps prevent the buildup of moisture, which can lead to dampness issues and damage to the building’s structure.
  4. Reducing Condensation: Adequate ventilation is essential in controlling condensation within a building. Airbricks contribute to this by allowing moist air to escape, reducing the likelihood of condensation forming on cold surfaces.
  5. Radon Gas Mitigation: In areas where radon gas is a concern, airbricks can be part of a radon mitigation system. These systems aim to vent radon gas from the ground to the outside, reducing its concentration within the building.

It’s important to note that while airbricks are beneficial for ventilation, they need to be installed correctly to ensure their effectiveness. Placement and sizing should be in accordance with building regulations and best practices to achieve optimal airflow and moisture control. Additionally, measures should be taken to prevent the entry of pests or debris through the airbricks, such as using mesh or grilles.
