Novia 1200G Vapour Control Layer
Our high strength virgin grade polythene vapour barrier
Novia 1200 VCL is a high specification, blown polythene material, suitable for use as a vapour control layer within the walls of timber frame constructions, or where control of the passage of water vapour is required.
This product also performs the additional function of an air-leakage barrier, to prevent losses due to unwanted convection flows. We advise the use of Novia butyl and metallised BOPP tapes to ensure a complete barrier integrity throughout the entire life of the product. For difficult areas to seal with tapes, or for additional support in certain applications, Novia AirSeal 310 is available. Novia 1200 VCL should be used in combination with Novia breather membranes to provide an air-tight and vapour resistant system.
Novia 1200 VCL is fully CPR compliant and is UKCA Approved to EN 13984.
Novia 1200 VCL is available on NBS Chorus and NBS Source software packages. Full information can be found for NBS specification with the table below. The links will open a pop up window with full specification information.

To install the membranes, we recommend using the Novia double tape system.
Our Double Sided Butyl Tape is used on the laps and edges of the membrane, with either Metallised BOPP Tape or Aluminium Foil Tape then used to complete the seal, keeping down any excess membrane which may get caught in the wind. For difficult areas to seal with tapes, or for additional support in certain applications, Novia AirSeal 310 is available.
