Visqueen Vapour Barrier is an ACVL (air and vapour control layer) and is used in medium condensation risk buildings to reduce the risk of interstitial condensation occurring within the structure as well as improving the airtightness of the building.
The barrier restricts the passage of warm, moist air within the building from permeating into the floor, wall or roof structure.
