Novia VariCheck FR Class B-s1,d0 Fire Rated Variable Vapour Check Air and Vapour Control Layer
Verified by manufacturer 1 month ago
VariCheck FR is a class B flame resistant, variable vapour check barrier, for use as an internal air and vapour control layer (AVCL).
Application
Suitable for use in insulated wall or roof applications and floor applications where a fire rating is not required.
Air and Vapour Control Layers (AVCL) should be installed on the warm side of the building envelope, within all insulated wall or roof applications and it is recommended to use Novia 30 mm double sided butyl tape and Novia 96 mm wide BS 476 cold weather aluminium foil lap tape.
Description
Novia® VariCheck FR is a class B flame resistant, variable vapour check barrier for use as an internal air and vapour control layer (AVCL).
Suitable for use in insulated wall or roof applications where low moisture vapour resistance is required.
The permeability of the membrane varies seasonally with changes to local humidity levels, as the membrane is less permeable in colder months, and more permeable in warmer months.
Features and benefits:
- CE approved to BS EN 13984.
- Fire classification to EN 13501-1, B-s1,do.
- Low cost, fire rated option for both standard and high rise constructions.
- Variable water vapour permeability, sd 0.4–3.2 m.
- Fully airtight air leakage barrier.
- Translucent material, for easy on-site installation to battens.
- Helps towards BS 5250 requirements.
