Jump to:
+44 (0)161 865 4444 www.wolfin.co.uk

A fleece backed homogenous roofing membrane that combines high robustness and great flexibility. The specially designed polyester fleece fabric provides both dimensional stability and resistance to high tensile forces. It has a fleece-free edge for accurate and impenetrable homogenous welding of one strip to the next. Tectofin RV is suitable for new build and refurbishment projects and can be applied to the roof by all fixing methods (mechanically fixed with screws, bonded with adhesive or retained with ballast and green roof options). It is CE marked and is available in light grey and titan (dark) grey.
