Visqueen Vapour Barrier
Visqueen Vapour Barrier is used to omit the risk of interstitial condensation within a structure as well as improving the general airtightness of the building. Visqueen Vapour Barrier restricts the passage of warm, moist air from within the building from permeating into the structure or the roof.
Visqueen Vapour Barrier should be installed on the "warm" side of the insulated structure, with special care being taken to ensure that all seams and holes are sealed effectively - thus rendering the whole structure moisture vapour proof and improving thermal performance. It is important that Visqueen Vapour Barrier should be continuous in order to prevent vapour entering the wall or the roof.
Visqueen Vapour Barrier is manufactured to NHBC standard (Clause 6.2) using virgin polyethylene.
