"New West Lake" brand fiberglass asphalt shingles (MPG1000 × 333) is the base of high-quality glass fiber mat for the child, after a quality oil asphalt dipping surface, one side covered with colored mineral granules calcined, spread the other side to isolate the material new tile-like roofing tile material. 1, the glass fiber mat is good or bad a direct impact on the period of asphalt shingles, GB GB/T20474-2006 the strict rules of asphalt shingles tire base of the glass fiber mat, the specification of not less than 90g / ㎡. Glass fiber mat is the most stable performance in all types of tire base, the greater the glass fiber mat weight in grams of the more glass content, the strength of a stronger, more stable performance, corrosion resistance can be enhanced;, asphalt formula crucial, because the intensity of exposure throughout the year in the Yang Guan climate temperature difference assumed test of the asphalt, asphalt shingles are generally self-adhesive series, which requires to ensure that asphalt shingles body reach The soft and flowing, not hard not to break under the premise of fixed to the roof tiles to play the function of self-adhesive strips, self cement on the roof in order to achieve the necessary wind performance, asphalt shingle manufacturing process is very one of the important technical indicators. Asphalt shingle formula produced the key depends on the manufacturers of raw materials used in the quality and technical level, only a good asphalt formula will protect the useful life of asphalt shingles; choice of color mineral aggregates is also very important, according to quality from good to (cost in descending order) can be classified as: natural sand and ceramic sand, sintered sand (calcined sand), stained the sand. The sand quality is directly related to an asphalt shingle color of the asphalt shingles in the future the role of the long sunlight exposure, wind wiper of nature gods long resistance, in a nutshell a direct impact on the appearance of the appearance of asphalt shingles and roofing. Fiberglass asphalt shingles are the most widely used in Europe and the United States use more than about 80% of the roof fiberglass asphalt shingles, and in our country is in a strong growth phase, for example, in recent years, Shanghai, Hangzhou, Nanjing and other cities flat to pitched projects specify the use of glass tile, it is the most useful features: waterproof effect and aesthetically pleasing, light weight (low roof affordability), easy construction, environmental protection, self-cleaning of dust, and strong corrosion resistance. Amount of asphalt shingles gradually increased, but the market has a gradient confusion, many manufacturers crazy profit, at the shout of high slogan but the use of inferior raw materials, and the freshmen factory technology is not up to the same as the waterproofing membrane, the products of these manufacturers After a virtual "packaging" has become a "good product" end products "In fact, the ultimate victims or consumers, to real estate developers, contractors and owners have brought a lot of trouble. I want to buy friends must keep their eyes open, carefully examine the good quality and then choose their own ideal cost-effective products! If necessary, the Building Materials Co., Ltd. Hangzhou crystal look to the actual production line to see
