Two-in-one insulating and breathable venting membrane. Suitable for timber frame and dormer walls. Effectively reflects heat back out of the room. Allows moisture to pass through, reducing risk of condensation. Up to 42% reduction in heat loss (based on a single layer in a timber frame). R-Value up to 0.79 m²K/W (equivalent to 35mm of Mineral Wool). Non-degradable for long-lasting thermal performance. Excellent tensile and tear-resistance strength. Two layer build-up and only 4mm thick. UV stable and weather-resistant. Flexible, lightweight and easy to install. Minimal waste compared to traditional insulation products. Zero fibres removes the need for PPE. Rolls can be sealed and joined together with foil tape. Fully Agrément-certified, Building Control-compliant and NHBC-accepted. Made in Britain
