Izospan Basic breathable membrane, 3-layer, 90 g/m², 80 m²/roll

Description

Breathable roofing membranes are used as the first covering layer of a pitched roof structure. They keep snow and rain out of the roof insulation and the structure itself, and protect against condensation forming under the roof covering. Thanks to their high vapour permeability they release the moisture that builds up on the inner side and keep the roof dry, which matters a great deal for a building’s energy use. Horizontal and vertical laps of the membrane should be taped.
