Visqueen Class B FR Vapour Check 4x50m

Visqueen Class B FR Vapour Check is an orange tinted, semi transparent modified fire resistant polyethylene AVCL (air and vapour control layer).

Visqueen Class B FR Vapour Check is used in buildings where an air and vapour control layer (AVCL) is required that achieves a reaction to fire classification B - s1, d0 to BS EN 13501-1:2018. The membrane is used to reduce the risk of interstitial condensation occurring within the structure as well as improving the airtightness of the building.

The membrane restricts the passage of warm, moist air within the building from permeating into the floor, wall or roof structure and is designed to be installed on the warm side of the structure.

• Fire Classification B - s1, d0 surpasses all national Building Regulations and standards for air and vapour control layers - suitable for all building heights including residential over 18m high
• UKCA UKNI Mark to EN 13984:2013 and Approved Document B - achieves Building Regulation and warranty provider requirements
• Third party tested to EN 13501-1:2018 - fully tested AVCL system (including tapes) for fire resistance
• Convenient 2.45m wide roll for wall applications - rapid installation reducing the need for horizontal lap joints
• Versatile application used within floor, wall and roof constructions - provides air tightness, water vapour resistance and reduces the risk of condensation
• Excellent puncture and tensile strength characteristics - robust for on-site handling and installation
