The Eurovent Magnum membrane is used as an initial covering for roofs in pitched, insulated, ventilated, also with full boarding. Due to its structure and durability, it is one of the few products on the market recommended also for slate covering. It protects the attic during roofing works, and after closing the roof system, it protects against moisture and rainwater (rain, snow, fog) blown under the roofing. The product does not require a ventilation gap between the membrane and thermal insulation (mineral wool, glass wool, etc.), i.e. the membrane may be in direct contact with the thermal insulation. It should be remembered that roof membranes are products for insulating sloping roofs, so it is advisable to install the thermal insulation of the attic as soon as possible, which will ensure the efficient operation of the roof system. The final roofing should always be installed on the membrane using a batten and counter batten. Extremely tear-resistant. Eurovent Magnum is a top-class product, therefore it is appropriately marked with the original label. The originality of the product is also confirmed by the prints made on the membrane, thanks to which its installation on the roof is easy and quick.
