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.
