Feature basics fiberglass roofing materials - the cheapest option. It is more durable than cardboard and does not rot. In the opinion of the Russian manufacturers of roofing and waterproofing materials - this group of materials based on glass fiber poorly suitable for use as a top layer of roofing and waterproofing coating. Typically, the construction of new facilities roll material based on glass fiber used in the lower layers of the coating, and materials based on polyester and fiberglass - as the top layer. Materials based on glass-, whose production in Western Europe is very large (about 1 / 3 of the market), in Russia at present underdeveloped. This is explained by a high proportion of materials of the first and second generation paperboard production patterns. Many producers to rebuild their inappropriate production of materials on the ground is not rotting in mind two factors: - low effective demand, especially in the regions - the existence of its own production of cardboard in the enterprises - manufacturers of roll materials. Fiberglass is 3-5 times stronger than glass fiber and, accordingly, are 2-3 times more expensive. This high-strength negniyuschaya basis significantly increases the lifespan of the material compared to the roofing material, and reduces the risk of damage to roofing and waterproofing carpet during the operation. Polyester as durable as fiberglass, too, does not rot and in addition allows for a much better grip with bitumen nasloykoy that even more improves the properties of the material. In addition, the polyester is a more elastic material than the materials made of fiberglass. Unlike fiberglass with their low elongation (2-4%), polyester base can lengthen to 15-30%, providing a solid structure of the roof covering in harsh environments. Expanding the use of materials based on polyester fabrics important in Russia, with its continental climate and frequent and significant seasonal and daily temperature fluctuations. In Western Europe the share of roll roofing and waterproofing materials based on polyester produced by more than half of roll roofing materials. An interesting solution for the production of rolled roofing material is to use as a basis of metallic foil - aluminum or copper. At the same foil located on the front surface of the material and serves not only the basis but also protects the asphalt layer from the sun, creates a decorative effect. Thanks to this material are characterized by high longevity by slowing down the aging asphalt binder. In conventional materials for protection against solar radiation used book a sprinkling of colored mineral (shale, ceramic) chips. Such spreading is more reliable than traditional sand and mica, and attach decorative materials. The use of rolled roofing material includes a device multilayer roof membrane. Many companies - manufacturers of roll roofing materials in recent years have begun to use another method, which consists in replacing the entire roof membrane a multilayer composite materials: for example, two layers of foundation and three layers of bitumen, which allows the roll roofing plank at a time. Types of roofing materials can be divided into four generations of roofing materials: I generation - the usual roofing material rolled roofing and waterproofing material obtained by impregnating roofing paper oil bitumen followed by the application on both sides of the canvas cover composition, consisting of a mixture of bitumen and filler cap, and spreading - ( GOST 10923-93) on paperboard (longevity of less than ten years, the number of layers of roof membrane three or five or more manual installation) to this type of roofing materials include: Ruberoid - it rolled roofing waterproofing material obtained by impregnating roofing paper with soft oil bitumen, followed by coating both surfaces of the refractory layer of bitumen. Glassine - roll bespokrovny material obtained by impregnating roofing paper with molten petroleum bitumen with a softening temperature not below 40 ° C. Serves as lining materials for roofing material and is used for vapor barriers. II generation - surfaced roofing material on paperboard (accelerated flooring roof membrane); to this type of roofing materials include: Rubemast - surfaced roll roofing material on board. Differs from conventional roofing asphalt binder content increased from the bottom of the canvas. This improves the ductility and fracture toughness, increases the longevity of the roof. Rubemast fit by thermal podplavleniya lower cladding layer (without the use of bitumen mastic) or via a plasticizing solvents (gasoline, kerosene, etc.) III Generation - bituminous materials gnilostoykih fundamentals of synthetic or glass fibers (increased strength and durability of coatings up to 10-12 years ); IV generation - bitumen-polymer materials gnilostoykih basics (reduced number of layers of roof membrane two to three, increased reliability and durability of roofing to 15-25 years). Generation III and IV generation of modern roll of bitumen-polymer materials on the basis of modern gnilostoykih roll roofing material produces a large number of enterprises. For these materials there is no single GOST, so each is produced by its technical specifications (TS). There is not even a unified system for marking roll materials, although in this respect, the largest producers being established uniformity. When marking, many companies use three-letter designation. mPervaya letter - the type of foundation: E - Non-woven polyester fiber (polyester), T - Fiberglass; X - fiberglass. The second letter - view of the upper cover: P - protective polymer film, K - broadcast with coarse mineral; M - fine-grained silty sand. Third letter - the kind of the lower cover: P - protective polymer film; M - fine-grained silty sand. In special cases, use indexes F - foil, C - Suspension (dusty broadcast with).
