Novia VC8 Reflective Air Leakage Barrier & Vapour Check Laminate 1.5m x 50m 75m2

Novia VC8 Reflective (air and vapour control layer) is a reflective, air-tight vapour check membrane designed for use in in insulated wall, roof and floor applications as an air-leakage and Vapour Control Layer (VCL). This Vapour Check Membrane is a reflective membrane, which when correctly installed can improve U and R values of insulation. 

Install on the “warm” (interior) side of your structure and pair with external breather membranes for the “cold” side. Secure with Novia tapes for a secure finish.

• Supplied unfolded, in rolls
• High reflectivity and emissivity helps improve U value
• 1.5m wide
• CE Approved to BS EN 13984
• Improves insulation performance

What is a VCL?

 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.
