When it comes to saving space and insulating effectively, SuperFOIL SFUF is the premium choice you are looking for.
Our underfloor insulation is created using the most modern technology and exceptionally high standards to help you insulate your property most efficiently. Designed after considering all types of underfloor heating, SuperFOIL SFUF is an incredibly versatile solution. It can be used under screeded or laminated floors, over and under suspended concrete or timber floors, or even for your underfloor radiant heating pipes—without ever having to compromise your space.
A certified 3-in-1 product, providing high-performing insulation, vapour control layer (VCL), and a radiant barrier—all within a single product.
Meet or exceed project requirements, whether used on its own or in hybrid solutions. Rigorous testing ensures compliance with the latest building regulations.
Multifunctional, lightweight and easy to install design that requires no specialist tools.
New build, retrofit, timber-frame and DIY projects to achieve maximum performance, while maintaining a slim profile.
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.

Read what our happy customers are saying about SuperFOIL
products and services.
Easy to use, cut to size without any waste once measured carefully. Something I've thought of doing for many years but, never got round to it. Intend to sit back and hope it preformed as promised, I'm sure it will since the product is hailed by the experts on energy performance and importantly enough for seven radiators. Definitely recommend. Thank you..
Product: Radpack
Superfoil products radically simplified achieving the required insulation ratings for our renovation / extension project. I was very keen to maximise internal space in both the dormer spaces and a very large flat roof avoiding tall external build up. The technical team provided detailed options and then were more than happy to iterate these to refine the final solution. I ended up using a hybrid solution of SF40BB and SF40 along with Vapour barrier and mineral wool. I would recommend speaking to the tech team – they certainly allowed me to get the outcome I wanted.
