FR Range - The Same High Performance, But With Enhanced Protection For Added Peace Of Mind

Our “FR” products offer the same U-values as our standard Multifoil range and have achieved a “class 0” rating for BS 476.


As with the majority of our products, our fire-rated range is a certified, 3 in 1 product. Not only will it provide high-performing insulation, but you also benefit from a much-needed vapour control layer and radiant barrier. What this means for you is that you protect your project from condensation and you can rest assured that your home will be at the right temperature, whatever the season.

SFNC - The Perfect Solution For Commercial And High Rise Building Projects


Our SFNC is the safest of the safe. It has achieved the highest euro class rating possible of A1 “Non-combustible”.  SFNC is produced from specially made, high-tech materials and is designed to be used in high-rise and commercial buildings. This product has been used in many high-profile builds (can be seen on our case studies page).


Despite its slim appearance, SFNC provides exceptional thermal performance and is fully flexible. As with all SuperFOIL products, it is quick and easy to install.

Pitched Roof

Tiled Roof and With Multiple Windows

SuperFOIL insulation is suitable for use in a variety of roofing insulation applications, including pitched roofs, and can be used as part of a warm roof, cold roof, or hybrid system design.

To ensure you achieve your desired performance SuperFOIL can be used on its own, in multiple layers, or in conjunction with other more traditional types of insulation such as glass wool or PIR.

SuperFOIL is typically installed as a continuous layer either above or below rafters as this avoids the performance losses associated with cold bridging from timbers that can reduce performance by up to 15%.

When installing simply roll out and staple the SuperFOIL across your rafters, where the edge of rolls meet, overlap the edges, and seal with SuperFOIL tape. Once taped and sealed, installed a counter batten to create an air gap then follow up with your next layer (typically plasterboard).


Flat Roof

SuperFOIL is ideal for use in flat roof projects due to its high vapour resistance and continuous method of installation.

With a vapour resistance of 1200MNs/g, SuperFOIL’s outer layers are over twice the performance of a typical 500gauge polythene meaning much less vapour is able to penetrate into your roof structure that would otherwise cause condensation. Combine this with SuperFOIL’s continuous install method either above or below joist’s and you achieve a high-performance seal to minimise the risk of condensation.

Installation is very similar to that of a pitched roof, simply stapling the product in place and ensuring that any gaps are sealed fully with SuperFOIL tape. When used in conjunction with a single-ply membrane no additional ventilation is typically required (A full condensation risk should be undertaken to ensure there is no risk).

SuperFOIL is ideal for use in solid wall and timber frame constructions be it new build or retrofit projects. Adding a single layer of SuperFOIL to a solid wall can take it from un-insulated to meeting & exceeding current building regulation requirements in as little as 70mm.

Our SF40 insulation is hugely popular for dry lining schemes with a single layer of SF40 achieving as low as 0.22U in a wall with no other insulation required.

SuperFOIL can be used either internally or externally on both solid & timber frame walls to achieve your desired performance. SuperFOIL is particularly well suited to timber frame constructions as studs provide the ideal framework to install onto with minimal build-up whilst achieving very high-performance levels.



SuperFOIL insulation can be used on all floor types but is ideally suited to suspended timber frame floors (If looking for solid floor insulation please see our SFUF).

By using SuperFOIL in your floor you are able to take advantage of low emissivity air spaces with a  downward heat flow. Whilst in roofs & walls performance stops improving at 13mm & 20mm depths respectively, downward heat flow air cavities keep increasing in performance up to a 300mm depth meaning you can achieve very high performance with minimal insulation requirements.

All SuperFOIL Insulation products are independently tested by notified bodies and 3rd party certified laboratories to comply with relevant UK building regulations for use as part of construction and European regulations such as CE/UKCA.

We are also part of the Quality Mark Protection scheme and the IAA, meaning you are protected when using SuperFOIL Insulation in your project.

SuperFOIL can be used in many different situations to meet or exceed the requirements of Building Regulations for virtually any project, we can also provide U-value calculations (free of charge) for elemental or SAP assessment methods

Here at SuperFOIL insulation, we are committed to increasing our sustainability in all our processes.

We have a new, high-tech production line in our warehouse allowing us to keep up with demand using UK manufacturing.
On top of this, our products are made from up to 40% recycled materials, namely recycled plastic drinking bottles which go into the wadding used in our insulation products helping to reduce the amount of new, raw materials being made.

We are significantly reducing the amount of plastic used in retail packaging as part of our waste management protocols, reducing the amount of waste going to landfill from our products as well as our warehouse and offices.
