Key Features

  • 3 in 1 - Provides, vapour control, radiant barrier and insulation in one product
  • Can be used directly below screed
  • Suitable for all underfloor heating types
  • Easy to install with minimal waste
  • Made from 40% recycled materials & fully recyclable
  • Suitable for use in roofs, walls & floors in new build or renovation
  • Can be used on its own, or in combination with other insulations - Can achieve any U-value

Our underfloor insulation has been specially designed with solid floors in mind. SFUF has a built in, protective layer, meaning you can put screed directly on top of the product without worrying about causing damage to the insulation. This makes it an excellent addition to that new underfloor heating system that you are installing!  

SuperFOIL’s underfloor insulation is extremely thin, measuring a grand total of 6mm in thickness ! Despite it’s sleek appearance, SFUF still delivers the high thermal performance that SuperFOIL is known for. Making it the perfect solution for installations where floor depth is limited. 

 

SFUF is slightly different to our other ranges. Due to the materials used, it is typically installed with the use of no air gaps and has minimal compression. However, that is where the differences end! Our underfloor range remains easy to install with minimal wastage, whilst still providing you a certified 3 in 1 product. 

SFUF can be used all around the home! Not only in your flooring applications, but also your walls and roof! It can be used either as a lone product, or in combination with other traditional types of insulation. This means that you will always achieve your target U-value! It meets all your needs whilst still being made from 40% recycled materials and is fully recyclable!

Floor Applications

SFUF insulation under floor install diagram

SFUF is the solution for solid floor projects. Measuring at just 6mm it gives a core R value of 0.8.  Unlike our multifoil products, SFUF does not contain wadding layers within its build up, which allows for less compression within a solid floor application.

The top layer of SFUF is made from a polythene membrane, this is so that screed can be applied directly to the product without causing any damage to the insulation. It is also ideal for use with either electric or water based underfloor heating systems. 

SFUF is easy to install, and is designed to be installed in a continuous layer. It is simple and quick to cut and fit into place. When using SFUF as a lone product with an underfloor heating system, we recommend to use clip rail fittings when laying your UFH pipes.  If you are using SFUF in combination with other insulation products (such as PIR), then pipe can be layed using typical pipe clips, placed through the SFUF and into the foam board. 

 

It can be used on solid floors and over or under joists on suspended floors.

Other Applications

flat roof SF19+ insulation

Although designed with flooring applications in mind, SFUF is a highly versatile product!

It can be used in walls, roofs or any project that has limited space but needs a high performance insulation. SFUF can help with thermal bridging issues, helping to make a project airtight and even sound insulating. 

 

 

 

 

 

Certifications

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

Thermal performance is confirmed by testing to BS EN ISO 12667, ISO 8301 by BBA ( British Board of Agrément), who are a UKAS certified body and are an internationally accredited laboratory. Furthermore we have a range of other accreditation’s to comply with UK, EU & CE regulations to provide added confidence and accelerate your building application process from highly respected bodies such as BBA, LABC, DIBT & ZAG.

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

Specific approved thermal test methods are required to comply with BR443 in Part ‘L’ of Building Regulations. On top of this performance SuperFOIL also helps by reducing air moment (to reduce heat loss through convection currents) and radiant barrier properties (to reduce heat transfer through radiation /solar gain) helping to keep you home warmer in winter & cooler in summer.
