Visqueen Class B FR Vapour Check is an orange tinted, semi transparent modified flame retardant polyethylene AVCL (air and vapour control layer). The product is 0.125mm thick (500 gauge). The membrane is supplied in centre-folded rolls 2.45m x 50m and multi-folded rolls 4m x 50m.

Features & Benefits

• Fire Classification B - s1, d0 surpasses all national Building Regulations for air and vapour control layers - suitable for all building heights including residential over 18m high
• UKCA UKNI CE to EN 13984:2013 - achieves Building Regulation and warranty provider requirements
• Third party tested to EN 13501-1:2018 - fully tested AVCL system (including tapes)
• Convenient 2.45m wide roll for wall applications - rapid installation reducing the need for horizontal lap joints
• Used in floor, wall and roof constructions - provides air tightness, water vapour resistance and reduces the risk of condensation

Usage

• 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.
• For conformity with the reaction to fire classification, usage of Visqueen FR Double Sided Vapour Tape must not exceed 11% of the area of the Visqueen Class B FR Vapour Check.
• For conformity with the reaction to fire classification, usage of Visqueen FR Single Sided Vapour Tape must not exceed 11% of the area of the Visqueen Class B FR Vapour Check.
• Care should be taken by the Designer to ensure suitability for applications other than those stated above. Visqueen Class B Vapour Check should be approved by all stakeholders prior to use.
