Novia Class B VariCheck FR AVCL

Product Overview

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 EN 13984 and is CE marked. 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. Novia® VariCheck FR is a low cost fire rated solution, for use within standard, high rise and high risk 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 product is milky white in colour, except for 150mm overlap lines.

*Valid for substrates with fire class A2-s1,d0 or A1 such as 12mm plasterboard, with no cavity between product and substrate. Product tested to EN 13501-1.

For projects that also require a fire rated breather membrane which complies to EN 13501-1, we offer several fire rated products. See datasheets for more product specific information.
