The Cavibrick is a moulded ventilator from Cavity Trays of Yeovil.
Cavibricks have integral louvres, deflectors and an internal back upstand to guard against water ingress.
Whilst traditional airbricks generally have two rows of 9 square 8mm x 8mm apertures, (Total airflow rating 1152mm²) the Cavibrick has louvres promoting an airflow rating of 7,500mm² – over 600% greater.
Meet ventilation requirements easily and at less cost.
Plus there’s a supporting range of duct and extension attachments.
