Breathable membranes are an important part of roofing systems, as they allow any moisture which is trapped between the insulation layers and the tiles to escape outwards, minimising the risk of unwanted damp. We sell breather membrane that offers an excellent level of vapour transport, helping to keep loft and attic spaces dry. In addition, our tile roofing felt can be used in similar manner to trap vapour before it condenses on the tiles and then drips back down into the roof cavity. Our roof membrane and roofing felt are sourced from reputable manufacturers and ready for fast dispatch. Get in touch for more information about our discounts for bulk purchases!
