A typical household produces 12-15 litres of water vapour from cooking and washing every day. Most of this, unless the house has been built recently with a vapour barrier installed under the plasterboard in bedroom ceilings, where it then migrates through the plasterboard. In houses where there is only traditional ventilated loft space and no insulation, heat rises up from below If ventilation is adequate. Then on colder days, surface condensation may form plus frost if it gets cold enough outside.
TLX Gold Insulating Breather Membrane is the only product on the market with BBA certification. In a few quick and easy steps, this unique product will improve the thermal value of your roof without risking condensation, and with little to no change in roof height.
TLX Gold has been designed for today’s roofer. Whether it’s a roof refurbishment or a new build project, TLX improves thermal performance and eliminates the risk of condensation. It vents moisture like a breather membrane and yet insulates like non-breathable PIR board, making it an Sd intelligent product (the more moisture present, the more it breathes). Therefore there’s no condensation risk with TLX Gold–not even without a vapour barrier!
TLX Multifoil insulation has been rigorously tested by independent, accredited laboratories against the latest British and European standards. It was also the first foil insulation to be approved by BBA Certificate of Agreement and our roofing and wall solutions were the first to receive LABC recognition with Registered Details status.
