Description

Novia® 500 Gauge VirginPoly is a virgin grade, single-ply polythene Air & Vapour Control Layer (AVCL) designed for use in insulated walls, roofs, and floors where there is a relatively low risk of interstitial condensation. Installed on the warm side of the building envelope, it minimises air leakage and moisture vapour penetration, helping to protect the structure and improve insulation performance.

Ideal for timber frame constructions, including garden rooms and buildings, Novia® 500 Gauge VirginPoly is translucent green for ease of installation and is fully compliant with BS EN 13984 and CE marked. When used in conjunction with Novia® breather membranes and properly sealed with Novia® AVCL tapes, it supports energy-efficient, condensation-resistant construction.

Where to use

Within the walls of timber frame constructions or where vapour control is needed: Novia 500G AVCL (Air and Vapour Control Layer) is good to use within the walls of timber frame constructions or where vapour control is needed because it effectively regulates the passage of water vapour through the building envelope. By providing a strong barrier against moisture, it prevents condensation from forming within the structure, protecting insulation and timber from potential dampness and damage. This control helps to maintain the thermal efficiency of the building and contributes to the long-term integrity of the construction.
