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