Floor Insulation

Up to one-tenth of a home's energy escapes through the flooring. Protecting your home can prove costly if you don’t carefully consider the correct insulation product! Expensive energy bills and excessive heat loss is often due to poor insulation underneath your property. Or, even worse, none at all. Investing in high-quality, professionally installed underfloor insulation will reduce draughts, energy bills and improve your home's energy efficiency. SuperFOIL’s innovative multifoil can be fitted with ease no matter the flooring type! Additionally, it will get to work instantly, increasing your home's temperature stability.

When you choose to invest in innovative insulation products, you’ll save money in the long run. You could see hundreds conserved over the years on energy bills.

Installation Of Internal and External Wall Insulation

Our insulation requires no specialist tools or excessive measuring. We offer all products with the aim that they’re quick and easy, designed to speed up your project. SuperFOIL SFUF insulation has been designed with all underfloor heating types in mind.


The SuperFOIL team can advise how you should approach protecting your property. Additionally, our qualified team can guide you through selecting the system most suitable for your property, ensuring you meet with current Building Regulations. Multifoil can be used alongside existing material, including rigid insulation foam and mineral wool insulation!


Our solutions perform well enough to be installed independently in new builds. Still, they can accompany current methods such as PIR insulation boards, rather than replace them.

Suspended Timber Floor Insulation

While you’re getting timber floors installed, you must consider how you can prevent heat loss and reduce heating bills. Without proper insulation and ventilation, homes can lose up to 10% of energy through their flooring. Mineral wool is a traditional material to pack around flooring joists, but bulky. With outstanding thermal performance, SuperFOIL offers an impressive alternative to insulation boards for your wooden floor. Whether it's used for retrofit or new build floor joists, our multifoil’s airtight technology guarantees to retain a comfortable, natural temperature.


Eliminating drafts and retaining warmth is one of high-quality insulation's fundamental elements. SuperFOIL suspended timber floor insulation is no exception. It can be used directly over joists, creating an airtight seal under your floorboards and preventing against vapour, moisture and rot.

Solid Floor Insulation

While solid flooring may seem less drafty than suspended timber, you still need to conserve heat with insulation material. Though a wide range of solutions is available, SuperFOIL offers the perfect system regardless of your floor finish. With our expertise and innovation, you can enjoy effective installed underfloor insulation from our team with minimal effort.


SuperFOIL SFUF insulation has been designed with all underfloor heating types in mind. Years of experience have allowed us to develop our product to an exceptional standard. We include a specialist polythene top layer to apply the insulation directly under screeding.
