RESIDEK N4 5500 WSL

RESIDEK N4 5500 WSL is a bituminous membrane made of bitumen modified with elastomeric copolymers combined with a polyester and glass composite reinforcement. The membrane is also UV resistant and does not require any additional surface coating. RESIDEK N4 5500 WSL is covered with a slates finish. The underside of the membrane has a polyethylene film. The membrane is 100% recyclable, partially made of DERBITUMEN, a raw material resulting from the recycling of application waste and old selected bituminous roofs. Its specific formulation combined with polymers gives it excellent properties of both technical and ecological durability.After end of service life, the membrane can be replaced or overlaid with an extended period of RSL for a total of 70 years
