Beschreibung
Zusammenfassung:	The invention relates to a new base interlining for producing roofing membranes which have to meet a wide variety of requirements. The new base interlining provides a sufficient mechanical stability, good perforation strength, good tensile strength and a high resistance to thermal stress, inter alia required for base interlining during bituminization. In addition, the new base interlining requires a considerable reduced volume of impregnating bitumen when producing bituminized roofing materials and therefore high costs of special bitumens for filling the base interlining can be avoided. Beside the new base interlining, a method for producing it as well as roofing membranes comprising the base interlining are subject matter of this invention.
