SFTV - Reflective Radiant Barrier Insulation
Verified by manufacturer 5 months ago
Thermal, vapour and air tightness barrier foil insulation for use on walls, ceilings and floors.
Application
Ideal for use in new-build, renovation, extension or retrofit projects in pitched and flat roofs, and walls.
Description
A certified 2-in-1 product, providing high-performing radiant barrier, and a vapour control layer — all within a single product.
Features and benefits:
- Acts as both a radiant barrier and vapour control layer.
- Reflects up to 95% of radiant heat, minimising solar gain and overheating in summer and retains heat inside the property during winter.
- High vapour resistance prevents warm air or water vapour from penetrating through the wall, reducing condensation and mould.
- SuperFOIL SFTV offers thermal performance values of 0.90 R-value for roofs, 1.31 R-value for walls, and 2.62 R-value for floors.
- Can contribute to reaching U-values of as low as 0.10 W/m²K.
- Multifunctional, lightweight and easy to install design that requires no specialist tools and creates minimal wastage.
- Reaction to Fire (Euroclass) Class F.
- SuperFOIL SFTV has undergone rigorous testing and third party certification to comply with the latest building regulations standards for use as part of construction and European regulations such as CE/UKCA.
- SFTV can be installed in combination with other insulation products.
- SuperFOIL SFTV is suitable for use in roofs, walls and floors in new build and retrofits.
- SFTV has a lifespan of 50+ years
