Novia VC2 AVCL (air and vapour control layer) is a technologically advanced and reinforced air-tight vapour check membrane with an sd value engineered specifically for use in insulated wall, roof and floor applications in timber-framed dwellings.

This product performs the additional function of an air-leakage barrier, to prevent losses due to unwanted convection flows. We advise the use of Novia double sided butyl tapes and metallised BOPP tape or aluminium foil tapes to ensure 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 VC2 AVCL should be used in combination with Novia breather membranes to provide an air-tight and vapour resistant system.

This product is CE Approved and CPR compliant.

Vapour Control Layers (VCLs) are used to manage the transition through the building envelope of naturally occurring moisture vapour, which is produced by general building use. Our range of VCL membranes is formulated with a wide variety of construction designs in mind, delivering specific solutions for various applications and requirements.

Novia VC2 AVCL 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.
