Visqueen NF-Vapour Barrier is an air and vapour control layer (AVCL) and is used in low, medium and high 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 from within the building from permeating into the floor, wall or roof structure.

The barrier is designed to be installed to the warm side of floors, walls and roofs. It is suitable for all BS 5250:2021 humidity classes including those with high internal humidities e.g. laundries and swimming pools.

Product Description:

Visqueen NF-Vapour Barrier is a co-extruded, multi-layer thermoplastic barrier, 0.4mm thick (400 micron). The membrane is transparent with a blue tint and supplied 2.4m x 43.5m in a single wound roll.

Features & Benefits:

  • Used within floor, wall and roof constructions
  • UKCA UKNI CE to EN 13984:2013 – achieves Building Regulation and warranty provider requirements
  • Suitable for all BS 5250:2021 humidity classes – prevents damage to structure and insulation
  • Single wound roll
