Eurovent Special roof foil is used as initial roofing for sloping, insulated, ventilated roofs. 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. It perfectly protects thermal insulation and also against dust, dirt and other pollutants. The product requires mini. 5 cm ventilation gap between the foil and thermal insulation (mineral wool, glass wool, etc.), i.e. the foil must not come into direct contact with the thermal insulation.
