MultiTX® is a family of high-resistance air and vapour barrier roofing membranes designed as a modern, cost-effective, lightweight alternative to traditional bituminous-based felts. The extended MultiTX® range consists of four distinct products, differing in weight and design: MultiTX® Plus (116g), MultiTX® Pro (146g) and MultiTX® Maxi (190g) are certified by the BBA for use in tiled and slated ventilated pitched roofs, in both supported and unsupported applications. MultiTX® Solar, which is designed specifically for integrated solar roofs, completes the family.
