Hearing the phrase “Construction industry” before the eyes immediately arises a picture with a tower crane, brick ..
Meanwhile, this concept denotes an entire industry, which provides the construction site with materials, equipment and tools, including roofing materials.
The materials that are used to arrange the roof are referring to sealing, that is, to those that are designed to protect building structures from precipitation. In addition, materials of this type must transfer temperature drops that are characteristic of our climate.
When using bitumen, and materials based on it, when laying it needed to be heated. And in the use guide there was a whole section on warming up technology. New technologies provide for the use of polyphracy binding substances and a change in the methods of their application on the basis. The use of this material and application technology allows you to create durable, non -rotting roofing materials. As a basis for roofing materials, fiberglasses are used, non -woven materials based on polyester.
In the process of manufacturing on both sides, the base is applied with a polyuretic – bitumen mixture, and then covered with a film or sprinkle, thus, the formation of the upper layer occurs. To increase the stability of the material to temperature drops and the effects of precipitation in the mixture, polymeric materials of the SBS and Polyolefines (Arctic polypropylene) are added to the mixture. Granite or shale crumb is used as sprinkling on the upper layer.
