B6149 (Type II, 920g/m²) is a direct weldable, double side PVC coated, high tenacity woven fabric designed to meet the stringent requirements of biogas plants compliant with TRAS 120 regulations. This membrane offers superior low permeability against methane, as well as additives to protect against bacterial digestion, chemical, thermal and UV degradations, resulting in a long lasting performance. This membrane also offers flame retardant properties, high solar reflection performance and durable electrodissipative surface finish, making it suitable for both inner membrane (gas barrier) and outer membrane (structural skin) applications. With these features, B6149 is the ideal choice for businesses looking for professional and reliable membrane solutions.
