Application and Technical Data

The Eurovent® MAGNUM roof membrane is used as an underlay for pitched, insulated and ventilated roofs, including roofs with full boarding. Thanks to its structure and high durability, it is one of the few products on the market also recommended for slate roofing. The product requires a ventilation gap between the membrane and the thermal insulation (mineral wool, glass wool, etc.), which means the membrane must not be in direct contact with the insulation. Installation of the final roof covering on the membrane must always be carried out using battens and counter-battens. It is suitable for use under almost all types of roof coverings, in particular slate, ceramic tiles, concrete tiles, metal roofing tiles and aluminium sheets.
