Products for building
MSL 98 vapour-permeable roofing underlay is used in pitched roof constructions. It protects the roof structure from water penetration and shields the thermal insulation from external moisture. MSL 98 also prevents heat loss through wind washing from the roof's insulation layer. MSL 98 is a two-layer product with very good tear resistance, as one of the layers consists of a strong polypropylene fabric.
MSL film meets the requirements of the European standard EN 13859-1:2005 and is CE marked.
