Provides high levels of ventilation into cavity walls and under floor voids
Provides 7,600mm2 of airflow per 9x3in airbrick
Can be stacked to produce 9x6in and 9x9in
The brick incorporates a front mounted grille to prohibit large insects gaining access but wide enough not to be blocked by debris, paint or water droplets
A mortar key around the edge of the airbrick ensures secure adhesion to the building fabric while a clip together facility provides a choice of ventilation sizes
Hepworth Terracotta airbricks allow the free movement of air to ventilate buildings. Terracotta airbricks can complement the external finish of a property and will weather well with the surrounding brickwork.
