Novia VariCheck FR is a Class B* flame resistant, variable vapour check barrier for use as an internal Air & Vapour Control Layer (AVCL). The material meets BS EN 13984 and is CE approved. Novia VariCheck FR complies to EN 13501-1 Fire Classification B-s1,d0*. Novia VariCheck FR is suitable for use in insulated wall or roof applications where low moisture vapour resistance is required. Also suitable for floor applications where a fire rating is not required.

Novia VariCheck FR is a low cost fire rated solution, for use within both standard and high rise constructions where a vapour check membrane is required. Novia VariCheck FR is a variable vapour check membrane, achieving sd values between 0.4m – 3.2m. 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. Novia VariCheck FR is available in 1.5m x 50m roll sizes.The product is milky white in colour, except for 150mm overlap lines.
