Novia 200 Reflective is a highly reflective vapour control layer (VCL) designed to help prevent interstitial condensation and improve R and u-values in insulated wall, roof and floor applications. A 25mm cavity is required within the building envelope to benefit from improved R and u-values. 

Features flame-resistant additives that mean the membrane will not readily ignite, with a high reflectivity and low emissivity surface. 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
  • Can deliver improved U values when properly applied
  • 1.5m wide
  • CE Approved and CPR Compliant

What is a Vapour Control Layer (VCL)

A vapour control layer (VCL), also known as a vapour barrier, is a material used in building construction to prevent the passage of water vapour through walls, ceilings, floors, or roofs. It is typically installed on the “warm” side of the insulation (typically the interior side) where it helps to control moisture levels within the building envelope. By blocking the movement of water vapour, a VCL helps to prevent condensation from occurring within the building structure, which can lead to issues such as mould growth, rot, and reduced insulation effectiveness.

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.
