Product Overview
Novia 1000 Vapour Control Layer is a medium specification, blown polythene material, suitable for use as a vapour control layer within the walls of timber frame constructions, or where the control of the passage of water vapour is required.
Sitting between the 500G and 1200G membranes with regards to thickness and quality, the 1000G Polythene remains fully CE Approved as a vapour control layer.
This product also performs the additional task of an air-leakage barrier, to prevent losses due to unwanted convection flows. We also advise the use of Novia double sided butyl tape and metallised BOPP tapes to ensure a complete vapour seal is maintained 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 1000 VCL should be used in combination with Novia breather membranes to provide an air-tight and vapour resistant system. This membrane is fully CPR compliant and is UKCA Approved to EN 13984.
Novia 1000 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.

Installation Tips
Installation guidelines can be found on the product datasheets using the links to the left.
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.
