Product Details

Novia 1000 is a polythene vapour control layer (VCL) and air-leakage barrier designed for use in wall, floor and roof applications. Install on the “warm” (interior) side of your walls, roof and floors to control moisture and condensation. Pair with external breather membranes for the “cold” side and secure with Novia tapes for a secure finish.

Vapour Control Layers (VCLs) are designed to manage the passage of moisture through a building's exterior walls, foundations and rooves and limit condensation within the interstitial layer “between” rooves, walls and floors. Particularly in high-humidity areas like the UK, water-laden air can condense on these structures causing damage over the long term, and reducing the thermal performance of insulation. It is advised to seal your Vapour Control Layer with double-sided butyl tape, followed by a BOPP tape to improve airtightness and increase the efficacy of the Vapour Control Layer. How do I Apply a Vapour Control Layer? A vapour control layer should be applied on the interior side of any wall, roof or flooring, over timber studs before the internal lining. It should be 100% sealed to the structure with double-sided butyl tapes, pre-applied to all areas where a fixing is to be made, and finished with metallised BOPP tapes to ensure a complete vapour seal. It is best used in conjunction with a Breather Membrane applied to the exterior side of the structure.
