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 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.
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.
