Radiant Barrier Vapour Control Layers - SFTV/SFTV1L
Our SFTV range provides you with a highly rated vapour control layer. The range has been tested and certified to achieve almost three times the performance of a standard vapour control layer. This higher level of resistance means that less vapour will be able to enter into your roof or walls, significantly reducing the risk of condensation.
SFTV is made from a highly reflective material, allowing it to act as a radiant barrier. What this means for you is that it helps to keep your home cool in the summer and warm in the winter
Reflective Breathable Membrane - SFBB
SuperFOIL also offer our breathable membrane, SFBB. With a low vapour resistance, it ensures that any vapour that enters the fabric of your home will escape without causing risk of condensation.
Unlike other breather membranes on the market, our SFBB can be used in both your roof and walls, meaning that you only have to buy one product to fulfill your project’s needs! Our breather membrane is fully watertight, giving you an added peace of mind that it will provide an efficient secondary barrier when the rain starts to fall.
Save Yourself Time and Money by choosing the right insulation for the job!

Applications
Roof
Both of our reflective membrane ranges are suitable for use in flat roof and pitched roof applications. You can even use both products together to create the perfect solution against condensation within your home. Our SFTV range will help prevent your rafters being exposed to moisture, which could lead to bigger issues such as rot. Whilst SFBB will then allow for any moisture within your roof cavity to escape safely away from your building.
Ensuring you have a high performance vapour control layer is especially important when working on flat roofs, this is due to the fact that the risk of condensation is much higher. Our SFTV is the perfect product for this. If you are worried, then contact our team of experts for your free, condensation risk analysis for that important peace of mind.
Installation of both products is quick and simple, with minimal wastage and no unnecessary cleaning up after! Simply roll out in a continuous layer and then staple into place! Job done!
Wall
Recladding or insulating your external walls? SFBB is the perfect breathable membrane for the job! SFBB is a mere 1mm thick but provides an instant secondary rain barrier whilst allowing for any moisture within the walls to escape. SFBB is rated ‘W1’ fully watertight which means it is the ideal solution for use in your walls. One use for SFTV is dry lining internally. It provides both thermal and vapour performance in one product.
By using a reflective membrane you will gain a radiant barrier which will help to reduce solar gain and improve the overall thermal performance.
Certified By:
All SuperFOIL reflective membrane 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.
Vapour resistance performance testing has been carried out by BTTG and wind uplift tests performed by BBA to ensure our products meet the highest standards possible.
