Eurovent Basic membrane is used as initial roofing for sloping, insulated, ventilated roofs. Suitable for renovation of roof and attic 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.
