Tyvek AirGuard Control Vapour Control Layer 50mtr x 1.5mtr

DuPont Tyvek AirGuard Control is a tough, transparent vapour control barrier that improves airtightness by reducing convective heat loss and air leakage while also minimising the risk of condensation in roof and wall insulation.

DuPont Tyvek AirGuard Control is designed to reduce uncontrolled air leakage and minimise convective heat loss in roofs, walls and floors.

A continuous layer of Tyvk DuPont AirGuard Control reduces air leakage by providing an effective vapour control barrier to control air movement and moisture infiltration around the habitable space of the building.
