    SuperFOIL is dedicated to crafting top-tier multi-foil insulation. The SF40 multi-layer foil insulation, featuring 19 layers of technical innovation, sets new industry standards for efficiency. Among these layers are two polypropylene-reinforced heavy outer laminated foils, twelve aluminium-coated reflective foil PET layers, and six loft quilt layers. With increased thickness and superior radiant reflective and air barrier properties, SF40 offers multiple advantages over traditional non-reflective insulation like glass fibre.

    Features and Benefits:

    • Enhanced thickness, radiant reflective and air barrier properties
    • Efficient use of space, aids insulation and reduces waste
    • Simple to install
