KEY FEATURES
Key Features
Reflective Membrane for added thermal performance.
Using a high performance VCL & breather membrane helps to reduce the risk of condensation.
Helps to reduce solar gain in summer & heat loss in winter.
W1 Watertight so can be used on roof & walls, new build or retrofit.
Using reflective membranes helps to reduce overall insulation requirements.
Quick and easy to install available in multiple roll sizes to suit project.
Our range of reflective membrane’s add a competitive edge over traditional membranes by serving two purposes. They provide both the VCL or breather membrane function whilst adding additional thermal performance to your build helping you to save money & space on insulation costs.
SFTV & SFTV 1L provide a very high performance vapour control layer. With a vapour resistance of 1200MNs/g SFTV achieves nearly 3 times the performance of a standard 500gauge polythene. Higher performance means less vapour will get into your roof or wall structure in turn reducing the risk of condensation significantly.
SFBB our breathable membrane offers the other side to the equation. It is fully W1 watertight so can be used on both roofs & walls unlike many breathable membranes means you only need one product for your project instead of 2. Its low vapour resistance of 0.115MNs/g means that any vapour that does enter your properties walls or roof will be able to easily escape rather than building up and forming condensation.

APPLICATIONS
Flat & Pitched Roofs
Both SFTV & SFBB reflective membranes can be used in flat roof & pitched roof applications. By using them together you create the ideal situation for modern day building. SFTV helps to stop the ingress of moisture to your rafters that can cause condensation and in turn rot. Whilst SFBB allows the escape of any moisture that does get into your roof cavity.
Providing a high performance VCL such as SFTV is especially important on flat roofs where the risk of condensation is much higher.
Walls
If your looking to re-clad or insulate your properties walls externally then our SFBB provides the ideal secondary rain barrier. The low vapour resistance of SFBB allows any moisture within your walls to escape whilst still providing a barrier to ingress of water. The use of a reflective membrane gives additional benefits by adding a radiant barrier that helsp to reduce solar gain and improve overall thermal performance.
When dry lining internally our SFTV provides the perfect solution adding both thermal and vapour performance.
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.
