Asphalt shingle is a tile-shaped roof waterproof sheet made of glass mat as matrix, after dip coatings with high-quality petroleum asphalt, one side is covered with colored mineral granules, and the other side is made by spreading insulation material. It has the characteristics of good waterproof and decorative functions, with multiple characteristics such as rich color, various forms, light weight, thin surface and simple construction. Asphalt shingle is a new high-tech waterproof building material. It is also a new roofing material used in building roof waterproofing.
Implementation Standards: GB/T 20474---2006
