Not only does it beat any multifoil competitor product's R-Value, but it also offers extreme cost-effectiveness, making it a fantastic choice for your insulation needs.
SuperFOIL are committed to building superior multifoil insulation. Combining an impressive 37 layers of technical innovation, this SF40 Multi-Layer Foil Insulation achieves maximum efficiency, surpassing previously thought possible values within the industry. These layers include two layers of polypropylene-reinforced heavy outer laminated foil, twelve aluminium-coated reflective foil PET layers and six layers of loft quilt.

What's more, this SuperFOIL SF40 Insulation comes with CE-certified vapour and water barrier outer layers, ensuring exceptional performance. With efficient use of space, it maximises your roof and wall insulation. With the strongest multifoil material, it also aids in installation, reducing waste and providing excellent value for your money. In terms of thermal resistance, it achieves outstanding rValues of 3.58m²K/W for pitched roofs, 4.04m²K/W for walls, 3.58m²K/W for flat roofs and 5.69m²K/W for floors.
Additionally, with a simple installation process, this Multi-Layer Foil Insulation can be fitted horizontally or vertically and requires a 25mm air gap. It can be easily cut with a knife or scissors to tailor to your specific needs, providing an air seal and radiant barrier. Thanks to the LABC registered detail, complying with Building Regulations is straightforward.
