Eurovent Classic membrane is used as a preliminary roof covering for sloping, insulated, ventilated roofs and also with full formwork. Also suitable for use in roof and attic renovation in "inverted technology". It protects the attic during roofing works, and after closing the roof system, it protects against moisture and rain water (rain, snow, fog) under the roof covering. The product does not require the use of a ventilation gap between the membrane and thermal insulation (mineral wool, glass wool, etc.), i.e. the membrane can be in direct contact with the thermal insulation.
