New build, retrofit, timber-frame and DIY projects to achieve maximum performance, while maintaining a slim profile.
SuperFOIL SF40’s reflective foil acts as a radiant barrier, preventing unnecessary heat gain or loss. The built-in VCL minimises the risks of moisture penetration, condensation, and mould growth. Additionally, the inbuilt insulated waddings act as an effective insulator, preventing heat from passing in or out of the house.
With SuperFOIL’s vapour control products, your property will always be protected from temperature fluctuation, cold spots and condensation, ensuring year-round comfort and savings.
Due to its multifunctional design, SF40 achieves maximum performance while maintaining a slim profile. Using SF40 in your project simplifies your insulation job, saving you space, time, and money on installation.
Compared to many traditional insulation types, SuperFOIL SF40’s ease of installation and flexibility minimise product wastage and installation time. Offering excellent value for money, our multifoil insulation is perfect for new builds, renovations, and extensions. It is versatile enough to be used in both domestic and commercial projects, regardless of the project’s size and scale. This means you only need to purchase one product to cover your roof, walls, and floor!
