Visqueen FB Vapour Barrier

Visqueen Fully Bonded (FB) Vapour Barrier is used to omit the risk of interstitial condensation within a structure as well as improving the general airtightness of the building. It restricts the passage of warm, moist air within the building from permeating into the structure or the roof and is commonly used within timber frame housing as well as commercial buildings. It is a tough multi layer reinforced HDPE membrane with an aluminium foil and is designed for use in roofs, walls and floors subjected to humidity levels less than 60% at 20°C (BS 5250: 2002 class 4 and 5 humidity conditions), e.g. domestic dwellings with high occupancy, sports halls, swimming pools, communal shower areas, laundries, canteens and buildings with wet industrial processes.

For installation and test results information please refer to the manufacturer's datasheet.
