Visqueen High Performance (HP) Vapour Barrier

Application

Used for high condensation risk buildings to remove the risk of interstitial condensation within the structure in addition to improving air-tightness of the building.

Description

A multi-layer reinforced polyethylene barrier with a 20 micron aluminium foil core. The barrier is coloured blue on the upper surface and silver on the reverse. It restricts the passage of warm, moist air from within the building from permeating into the structure or the roof.


Features and benefits:

  • Versatile application.
  • Suitable for BS 5250:2011 class 4 and 5 conditions - prevents damage to structure and insulation.
  • Single wound roll means rapid installation.
  • Reduces the likelihood of interstitial condensation.
