Bituminous melt-bonded roll coating is used for installing the lower layers of roofing and waterproofing of building structures. The coating is made by coating a reinforced polyester fiber base on both sides with a binder made of SBS (styrene-butadiene-styrene) polymer-modified bitumen. The material is covered from the bottom with a protective layer - a polymer film, and from the top - with fine-grained sprinkle (quartz sand). (Turkey)

Bitumen coating is made by coating a reinforced polyester fiber base with a binder of SBS polymer-modified bitumen on both sides and is used for installing the lower layers of roofing and waterproofing of building structures. The material is covered from the bottom with a protective layer - a polymer film, and from the top - with fine-grained sprinkle (quartz sand). (Turkey) This melt-on-roll coating of the lower layer performs a waterproofing function, but does not protect against sunlight and cannot be used as the final finishing layer of the roofing. On these materials, it is always necessary to lay a top layer with coarse-grained slate sprinkle.
