Originally designed for solid floor applications, SFUF’s high-performance insulation isn’t limited to floors; it’s a versatile solution for roofs, walls, and floors. Thanks to its highly efficient 3-in-1 design, SuperFOIL SFUF provides high-performing insulation, a vapour control layer, and a radiant barrier. This significantly helps improve the U-value, comfort, and energy efficiency of your property without increasing your floor depths.
When installed properly, the highly reflective SFUF offers multiple benefits for your home, including optimal thermal performance, energy conservation, minimising thermal bridging, and even impressive sound insulation (reducing noise by up to 22dB). SFUF’s exceptional high standard includes a specialist polythene top layer, allowing direct application under screeding. The built-in protective layer means the top can be screeded without worrying about damage to the insulation. The grid markings on the foil make installation effortless and time-saving.
Due to its lightweight, flexible, and versatile design, SFUF is perfect for all underfloor insulation applications across domestic or commercial projects, regardless of the size and scale. When installed with minimal compression and without air gaps, SFUF creates an airtight project and provides a thermal break, even in areas difficult to insulate using traditional insulation materials. A cost-effective and slim alternative to bulky and heavy insulation types, SFUF is quick and easy to install and can meet all your project requirements for new builds, extensions, or retrofit projects.
