NORDBAR
Vapour retarder and vapour shield bituminous membranes
NORDBAR are vapour retarder and vapour shield bituminous membranes, made from a woven non woven polyester impregnated with a distilled polymer bitumen compound. NORDBAR guarantees a good breathability and assures to the structure a very good level of vapour permeability, even though it provides a sufficient water impermeability (on roofs with not less than a 40% slope).
