Visqueen expands fire protection range

Visqueen – which says that its air and vapour control layer system ‘combines strength, flexibility, and easy installation while exceeding current national fire safety regulations’ – has expanded its fire protection range by launching Visqueen Class B FR Vapour Check, an air and vapour control layer (AVCL).

The company explains that the complete AVCL system, including fixing and jointing tapes, achieves fire classification Class B – s1, d0 to EN 13501-1:2018. as well as zero air leakage to BS EN 1026:2016 when tested by third party independent laboratories, Warringtonfire and the British Board of Agrément respectively. Semi-transparent for ease of installation, and orange tinted for ease of recognition, the new AVCL is a fire-resistant polyethylene for use in all buildings, including residential, over 18m high where an AVCL is required within the floor, wall, and roof constructions.

Visqueen says it  reduces the risk of interstitial condensation occurring within the structure, and improves building airtightness. Key to the design of the Class B FR Vapour Check was the development of a flexible solution that is much easier to apply and detail. The 0.125 mm thick (500 gauge) AVCL is available in convenient centre-folded rolls of 2.45 x 50 m, and multi-folded rolls of 4 x 50 m. The 2.45 m wide rolls are said to  ideal for wall applications, enabling easier transportation and rapid installation, all while reducing the need for horizontal lap joints. The Class B FR Vapour Check has the UKCA UKNI Mark to EN 13984:2013, meeting both Building Regulation Approved Document B and warranty provider requirements.
