Visqueen Class B FR Vapour Check - Air Vapour Control Layer membrane
Verified by manufacturer 4 months ago
DoP
Certificate type
A fire resistant air and vapour control layer membrane.
Application
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.
Description
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.
Features and benefits:
- Fire Classification B-s1, d0
- Suitable for all building heights including residential over 18m high.
- CE UKCA Mark 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) 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.
Approvals and standards:
- System achieves a reaction to fire classification B-s1, d0 to BS EN 13501-1:2018.
- Air leakage to BS EN 1026:2016.
