Visqueen Vapour Check is used to omit the risk of interstitial condensation within a structure as well as improving the air tightness of the building.
Choose the best way to buy this product:
Visqueen Vapour Check restricts the passage of warm, moist air from within the building from permeating into the structure or the roof. Visqueen Vapour Check is manufactured using virgin polyethylene.
Suitable for preventing condensation in buildings which can lower the performance of insulation:
• Used within floor, wall and roof applications
• Vapour resistance of 266MNs/g
• Helps to prevent mould and damp staining
Ensure all surfaces are clean, smooth and dry prior to the application of Visqueen Vapour Tape or Visqueen Vapour Edge Tape. Surfaces do not require priming prior to tape application. For total protection, all joints in the vapour control layer should be lapped by a minimum of 75mm, and sealed with Visqueen Vapour Tape applied equidistant over the lap. To aid formation, laps should be made over a solid substrate.
For protecting and sealing the perimeter, Visqueen Vapour Edge Tape should be used. Where perimeter detailing involves sealing to masonry units such as brickwork, blockwork, etc ensure vapour proof continuity by sealing with Visqueen Vapour Edge Tape applied equidistant over the junction.
Visqueen Vapour Tapes are coated with a special cold weather adhesive system which combines superior quick stick at normal temperatures with superior low temperature performance below freezing. The tapes are highly puncture and tear resistant. Failure to suitably connect the vapour control layer to other building elements will seriously reduce performance.
