SF6 Multi-Layered Foil Insulation from SuperFOIL is a high-performance multi-layered reflective foil insulation for walls, floors and roofs. Designed to be space-saving while retaining excellent insulating properties, the foil uses highly reflective surfaces to create a radiant barrier returning heat into the home. The thermally resistant internal layers further limit all forms of energy transfer. Lightweight and flexible, the foil is very easy to transport and install- applied in a continuous layer there is no need to cut and fit small pieces between rafters or joists. The two-way radiant barrier function prevents heat loss in winter, reducing energy bills. In summer, the foil insulation reflects excess heat and solar gain to keep living spaces cooler and significantly reduces draughts and regains control over the internal environment. The foil insulation is suitable for a wide range of applications and DIY projects. Ideal for use in lofts, garages, basements, pet homes, sheds, garden
