Novia VC8 Reflective Air Leakage Barrier & Vapour Check Laminate

Novia VC8 Reflective Air Leakage Barrier & Vapour Check Laminate

Novia VC8 Reflective is a technologically advanced reflective air-tight vapour check membrane designed specifically for use in insulated wall, roof, and floor applications in timber-framed dwellings. It is a part of Novia's range of Vapour Control Layers (VCLs) that are used to manage moisture vapour transition through the building envelope. The Novia VC8 Reflective membrane offers several key attributes of a reflective VCL. It provides improved μ values, which refers to the permeability of the material to water vapour diffusion. This helps in managing and controlling the movement of moisture within the wall and ceiling structures, preventing condensation and protecting the building envelope from damage. Unlike traditional reflective vapour barriers that have high water vapour resistance, Novia VC8 Reflective is designed with a carefully chosen Sd value of 6m. The Sd value is a measure of the material's water vapour resistance. By balancing the Sd value, Novia VC8 Reflective effectively manages water vapour diffusion without suffocating the structure with a membrane that has an undesirably high vapour resistance. This approach helps improve indoor air quality compared to traditional reflective vapour barriers. To ensure the integrity of the barrier throughout the entire life of the product, Novia recommends using compatible butyl and foil sealing tapes. These tapes should be used to seal any joints or overlaps in the membrane, creating a complete barrier system. It is important to note that Novia VC8 Reflective should be used in combination with Novia breather membranes to provide an air-tight and vapour-resistant system. The breather membranes allow the building to release any trapped moisture while still providing a barrier against external moisture ingress. Novia VC8 Reflective is CE Approved and CPR (Construction Products Regulation) compliant, indicating that it meets the necessary European standards for performance and safety. Overall, Novia VC8 Reflective offers a technologically advanced solution for managing moisture vapour in timber-framed dwellings, providing protection to the building envelope while improving indoor air quality.
