COPERPOL EXTRA is a top grade modified bituminous waterproofing membrane made of distilled bitumen modified with state of the art poly-olefins and selected copolymers (APAO), that make it an extreme product in terms of resistance to UV, adhesiveness, flexibility at low temperatures and resistance to ageing factors. COPERPOL EXTRA is the most advanced product manufactured by Copernit at this time and it has been designed for use by professionals in applications where the waterproofing layers must withstand the most severe weathering and adverse climate conditions as well as static and dynamic forces.
COPERPOL EXTRA has a tough isotropic and rot-proof spunbond polyester carrier, reinforced and stabilised with longitudinal glass yarns that provide superior dimensional stability and reduce to an absolute minimum the risk of shrinkages caused in time by weathering and by swift thermal excursions.
