A traditional specification, single-ply, non-laminated, virgin grade blown polythene material. It is designed for use as an air leakage barrier and vapour control layer (AVCL) in insulated wall, roof and floor applications.

All Novia® VCL products should be 100% fully sealed to the structure using a Novia® double-sided butyl tape, and one of the foil or BOPP lap tapes to professionally complete the installation. The wider the tape used, the stronger the final seal will be, and the easier it will be to install.

Novia® recommends the 30 mm wide butyl tape and 60 mm metallized BOPP tape for all standard VCL installations.
