Novia 1000 gauge VirginPoly / 250 micron virgin grade polythene Air & Vapour control layer (AVCL).
For use as an air and vapour control layer (AVCL). Suitable for all SFS light steel frame, timber frame and concrete frame insulated wall constructions. Also used in insulated pitched roofs and floor applications. Novia manufacture different gauges of virgin grade VCL to ensure the correct products meets the requirements of the building. Take a look at www.novia.co.uk for more details and our other vapour control layer and air tightness membrane options available to you.
A traditional, single-ply, virgin grade blown polythene material. Supplied in a 4m x 25m roll size it is ideal for use in Insulated wall, floor or roof applications where there is a moderate risk of interstitial condensation occuring, also minimises air leakage and energy heat losses, improving the long-term energy efficiency of constructions. Provides an airtight seal, it must be installed in conjunction with the Novia two-tape sealing system.
