One-layer roofing materials

Description: These are roofing and waterproof fibers intended for the installation of single-layer roof cladding. The materials are produced by two-sided placement of mineral filler (talc, dolomite and others) and fire-retardants on a reinforced polyester foundation with bitumen-polymer cement, which is composed of bitumen, a SBS (styrene-butadiene-styrene) polymer modifier. A coarse-grained dressing compound (slate, aluminum-added slate or basalt) can be used on the top as a protective layer. A protective film or a nonwoven fiber is attached on the bottom surface.
