The safety and environmental characteristics of insulation materials determine the overall trend of industry development. At present, the energy loss of housing in China is roughly 50% of the wall; the roof is about 10%; the doors and windows are about 25%; the basement and the ground are about 15%. Therefore, the insulation of the wall and roof is to improve the building energy efficiency. An important part of the rate. How to choose a wall insulation building material that is both safe and environmentally friendly is the key to today's industry and decides the sound development of China's building energy-saving insulation materials building materials industry.
Under the requirements of environmental protection and environmental protection of residential buildings, the energy conservation rate of buildings in China has increased year by year. However, at present, China's building insulation materials, especially for exterior insulation materials, are mainly organic materials, of which the market share of polystyrene is 90 and that of polyurethane is 10. However, due to the nature of the materials and various fire prevention measures and management measures, In place, fire accidents have occurred.
In order to ensure safety, the Ministry of Housing and Construction and the Fire Department of the Ministry of Public Security jointly promulgated the Interim Provisions on Fire Protection of Exterior Insulation and Exterior Wall Decorations for Civil Buildings in September 2009. In the provisional regulations, for residential buildings with a height of 100 m or more, public buildings with a height of 50 m or more, and curtain wall buildings with a building height of 24 m or more, the burning performance of the insulating materials used shall be Class A.
The so-called A-class, that is, non-combustible materials, but currently the popular building insulation materials in the market in China are mainly organic materials, even if the flame retardant is added, the highest can only reach the B1 level. If we strictly enforce the most stringent fire protection order in history, it means that China's thermal insulation materials industry will face a situation of reshuffle or even elimination. Therefore, thermal insulation materials, especially external thermal insulation materials, have considerable market capacity, which can bring greater business opportunities to manufacturers engaged in exterior insulation materials.
