What is asphalt shingles?

Asphalt shingles, also known as shingles, shingles, fiberglass tire asphalt tile. Asphalt shingles is a new high-tech waterproof materials are also used in the construction of a new type of roof roofing material.

Introduction asphalt tile
Humans since ancient times, gone through the roof tile changes. Asphalt shingles as a domestic new type of roofing materials in foreign countries has a long history. 150 years ago, some people in North America with asphalt products manufacturing shop in the ramp on the roof. Fiberglass asphalt shingles is a tire for the matrix of glass fiber mat, after dipping high-quality asphalt surface, the side cover colored mineral granules, on the other hand spread to isolate a new type of sheet material made of roofing tiles. It has a waterproof and decorative features, well architects, property developers, design institutes and the general consumers, is currently widely used in sloping roof of the new waterproof decorative tiles. In the United States, asphalt shingles are the most widely used roofing products, information, U.S. production of asphalt shingles each year more than 1.4 billion square meters. However, to differentiate the product is often difficult, because the manufacturer refused to disclose the relevant technical information. The twentieth century in the late nineties, China's Shanghai, Dalian, China, the rise of the "flat to pitched" hot, flat roof almost all along the street have changed to pitched roof, the city a new look. Serves as the main slope roof material is asphalt shingles, is characterized by its maximum weight, the color is greater. Asphalt shingles is a glass mat for the matrix, by dipping high-quality asphalt, the side cover color mine without aggregates, on the other hand scatter to isolate the tile made of materials like roofing sheets, it has good water , decorative features and rich colors, forms, light and surface details, construction and simplicity. Asphalt shingles is a kind of decoration and waterproof roofing. In the United States and Canada production and use of large, mainly for residential and commercial buildings in the sloping roof. Production in Europe to use asphalt shingles, but relatively smaller quantities. Twentieth century China, Shanghai, Ningbo, introducing the foreign advanced technology of asphalt tile production line, opened the first of its kind domestic production of asphalt shingles, and Hangzhou, Ningbo and other places of the asphalt tile company has rise. The twentieth century, Shanghai and other coastal cities, such as "flat to pitched," became the preferred color of asphalt shingle roofing materials. This not only changed the urban landscape, but also improve roof drainage and insulation properties. The twenty-first century, the production and use of asphalt shingles have a greater development in China. Hangzhou, Ningbo and Shanghai, some companies produce asphalt shingles or part of the introduction of production line equipment, but most enterprises in the production of modified bitumen membrane production line transformed the production of asphalt shingles, the annual output of about 30 million square meters in 2500 (construction area). As the asphalt tile beautiful, lightweight, waterproof performance, easy transportation, installation, etc., in Shanghai, Zhejiang, Jiangsu, Shandong and Liaoning provinces and cities are promoting the use of large areas, and even inland areas of China in Xinjiang, Inner Mongolia, Heilongjiang provinces, autonomous regions and also used for asphalt shingle roofing materials for residential buildings, and some exported to Russia, South Korea. Colored asphalt shingles as the twentieth century, the twenty-first century roofing materials in China, "the new darling." Use one city, "flat to pitched" project, coastal city, Shanghai, Hangzhou and other places with higher usage; second urban residential housing sloping roof; third, luxury villas and the sloping roof.

Standard of asphalt shingle
ASTM International standards have 2 for the existing asphalt shingles in the United States products: ASTMD225 "mineral aggregate surface asphalt shingles (organic felt) the technical conditions" and ASTM D3462 "mineral aggregate surface asphalt shingles (fiberglass tire) the technical conditions" . This is two standard specifies the minimum and maximum asphalt shingle quality, physical properties and function, and the International Building Code and NFPA 5000 "Building Construction and Safety Standards" are adopted as minimum requirements for asphalt shingles. According to the NRCA 2005-2006 Guide steep slope roofing asphalt shingles of the data analysis revealed that all 13 of the matrix of organic felt asphalt shingles are in line with ASTM D225, 104 个 fiberglass shingles with 91 fetal meet ASTM D3462. China's national standard asphalt shingle "fiberglass asphalt shingles child" has been approved by the State Committee for Standardization, Standard No. GB/T20474-2006. On February 1, 2007 implementation. "Fiberglass asphalt shingles tire" built by the Chinese Suzhou Water Institute, the National Monitoring Centre and the China Building Materials Waterproof Building Materials Industry Association, as editor of units by domestic enterprises participated in the preparation, preparation of the last 4 years.

Distinguish between asphalt tile
Although asphalt shingles generally consistent with the current ASTM standard, but few manufacturers that their products are often more than A5TM index requirements. On the guide data analysis showed that 20-year period of asphalt shingles to ensure the quality and physical properties of 50-year guarantee period with almost the same. While most high-quality asphalt shingle product quality and physical properties of more than ordinary asphalt shingles, roofing professionals, but is difficult to obtain information on these technologies. Effective way to differentiate products is required by standard test methods.

Asphalt tile test
Test the wind exposing the provisions of the method according to ASTM D3161 and D3462 in accordance with ASTM D225 under wind speed 27 m / s measured, of course, the method also applies to the determination of when the high wind speed. By ASTM D3161 method with wind speed 40 m / s products for the D level, through 49 m / s for the F class. Guide to a total of 117 products, including manufacturers, said 18 to F-class, this information is not public. Alternatively, UL 2218 "Roof cover the impact tests," simulated by the hail product can be used to distinguish asphalt tile. Guide 9 of 117 products meet UL 2218 alleged the four, this - the information has not been made public. For users, in addition to the guarantee period should be outside in order to obtain information to manufacturers differentiate.

Asphalt tile structure asphalt shingles
Sandwich design a unique, natural, ceramic granules protect the asphalt surface from direct sunlight, so that the aging of asphalt is not easy, free from wind and rain erosion, and rich colors of products to enhance the beauty of the roof, and provide good fire performance. 2, asphalt shingles,all-weather modified asphalt waterproofing coating and colorful glass tiles can withstand wind and rain erosion for long periods, protect the roof from moisture effects, and also in the severe cold and heat to maintain product performance. 3, glass fiber tire-based products have not only excellent water resistance, even if the tile surface has been damaged, and colorful glass tiles are also able to maintain water resistance, and ability to weather and fire optimizes performance so that more tough and durable product, which Avoid products in the production, transportation, construction and use of the damage occurred. 4, hot melt glue from the automatic activation by heat, so colorful glass tile and the next layer of colorful glass tiles firmly bonded together, fused, to ensure the integrity of the roof, dense impermeable.
