Description
The SuperFOIL SFTV Thermal Vapour Barrier (VCL) – 1.5m x 25m (1875m², 50 Packs) is a high-performance vapour control layer and radiant barrier designed to improve energy efficiency and moisture management in walls, roofs, and floors. Featuring a reflective metallised polyester finish, this lightweight polypropylene membrane helps reduce heat transfer while controlling the movement of water vapour through building structures.
SuperFOIL SFTV provides a 2-in-1 solution by functioning as both a vapour control layer and a radiant barrier. Installed on the warm side of insulation systems, it helps prevent condensation build-up, protects insulation performance, and improves thermal comfort throughout the year. With R-values ranging from 0.95 in roofs to 2.80 in floors, it is suitable for a wide range of construction applications.
Supplied in a bulk pack of 50 rolls, SuperFOIL SFTV is ideal for large-scale projects including new builds, extensions, and renovations. Easy to handle and install using basic tools, it provides an effective solution for creating airtight, moisture-controlled building envelopes.
