Wall and Underfloor Ventilation

Cavity Walls and Voids below floors need to be ventilated in order to prevent the build up of damp, mould and unwanted and hazardous gases.

Our Air Bricks, Sleeves, Weep Vents and Underfloor vents are cleverly designed to adapt to a number of different situations whilst still being simple to install.
