Current, energy conservation has become the consensus of the international community, and the development of low-carbon environmental sustainability a top priority of China's economic and social development.
In 2005, the Ministry of Construction issued a public building energy efficiency design standards and strict implementation of energy efficiency design standards for new residential buildings, domestic construction in 2010 to achieve a 50% energy saving target. Building insulation materials compulsory certification system in the country, without making the outer insulation of the project shall not be acceptance. The energy saving rate of 50%, you need a comprehensive transformation of the building's exterior wall insulation materials market will increase significantly. Thus forming a new type of energy-saving building materials industry shows a very broad market prospects. Energy-saving building materials, especially the wall and roof insulation materials, a huge market.
As a result, the domestic insulation market has entered a golden period of development, both organic insulation system or inorganic insulation system, has made rapid progress. However, since 2009, less than two years time, the North Side Building of the new site of CCTV, Shanghai Jiaozhou teacher apartment, Harbin Petronas Twin Towers, Jinan Olympic Sports Center and other famous landmark due to the use of combustible organic insulation materials caused fire, causing heavy casualties and property losses. A series of accidents, flammable and combustible organic insulating material, such as EPS board, XPS board, polyurethane material, look to re-market management.
View of flammable organic insulation materials unavoidable defects, the Ministry of Public Security issued a "civil exterior insulation system and external decorative waterproof Interim Provisions" ([2009] No. 46), which provides civil construction outside insulation material is to be used for the combustion performance as A grade material. The introduction of this provision, the organic insulation materials can only meet the fire safety standards of the Class B encounter cold, shrinking market. In contrast, achieve a Class A fire safety standards have incombustible inorganic insulation materials ushered in the climax of development, which, with its excellent thermal insulation properties of expanded perlite has become the new darling of the inorganic insulation market, a huge market demand.
