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.
Drybase Liquid-Applied DPM is a single-pack barrier coating for above ground use. It is supplied ready to use. It is available in black or white with a consistency similar to that of thick emulsion paint. The product is applied in two coats. Drybase Liquid-Applied DPM Is suitable for use on solid floors, embedded timbers and walls. Once applied, the product cures to form a membrane that is flexible and elastic. Drybase Liquid-Applied DPM is water- based and can be applied to damp substrates by brush, roller, or spray. The applied product is typically touch-dry in one hour.

Used to drain lintels, Cavity Trays, and to ventilate cavity walls
Please note: This item is a plastic component and therefore is not suitable for use within a) the external walls of buildings more than 11m high where people sleep on the premises (residential, institutional or hospitality) or b) external wall surfaces within 1m of the boundary if the building is 11m high or less, in England. For a compliant alternative see Rytons A1 Fire Rated Metal Rytweep Cavity Weep Vent.
This wire cut perforated engineering brick from Wienerberger has a durability rating of F2, meaning it is long lasting. Suitable for walls, pavements and other kinds of masonry construction.
