Terracotta Air Brick 9x3

Modern construction using higher levels of thermal insulation requires increased levels of ventilation within the building fabric to prevent the build-up of moisture and condensation.

The Airbrick has an airflow of 6,000mm² and should be installed at a maximum of 2m centres. To provide a greater airflow it is possible to clip together a number of vents in a vertical stack. The Airbrick should be used in combination with one of the cavity sleeves illustrated to provide through wall ventilation.

• Ventilation area 8000mm2
• Driving rain resistant. 
• Standard brick face dimensions. 
• Injection-moulded components. 
• Can be stacked in multiples.
