Novia VC8 VCL


New generation reflective VCL and Air-Leakage Barrier

Product Overview

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 VC8 Reflective is a technologically advanced reflective 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 new product delivers the key attributes of a reflective VCL, i.e. improved  μ values, interstitial water vapour condensation management and prevention of unwanted air-leakage, but without suffocating the structure with a membrane of undesirably high water vapour resistance. Novia VC6 Reflective effectively manages water vapour diffusion and limits unwanted condensation within wall and ceiling structures, protecting the building envelope from damage. Due to the innovative manufacturing and design parameters of the VC6 Reflective and its carefully chosen Sd value of 6m, indoor air quality is improved when compared with traditional reflective vapour barriers which have unsuitably high vapour resistances.


We advise the use of Novia compatible butyl and foil sealing tapes to ensure a complete barrier integrity throughout the entire life of the product. Novia VC8 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.
