Airbricks are designed to provide high levels of ventilation into cavity walls and under floor voids. The brick incorporates a front mounted grille with water deflectors. A mortar key around the edge of the airbrick ensures it can be securely fixed to the building fabric and a clip together facility provides a choice of ventilation sizes. The product is suitable for use with gas appliances.
