The fires that followed one after another were the focus of everyone's attention, and the construction of insulation materials as the "accomplice" of the combustion improver was pushed to the trial stage of public opinion. In mid-March 2011, the Ministry of Public Security issued the Notice on Further Clarifying the Relevant Requirements for Fire Supervision and Management of Civil Building Exterior Insulation Materials (hereinafter referred to as Circular 65). Two points have been clarified: First, the external thermal insulation materials for civil buildings will be included in the fire protection design review, fire inspection and filing inspection scope of the construction project; secondly, the external thermal insulation materials for civil buildings shall be made of materials with a burning performance of Class A. According to industry insiders, the fire protection standard of Circular 65 was forcibly promoted, which is the most stringent standard for building insulation materials in history.

It is a general trend for the relevant departments to implement higher standards of building insulation materials. Due to the issuance of Document No. 65 of the General Administration of Fire of the Ministry of Public Security, it has brought tremendous impact to the construction and building materials markets.

Traditional and non-standard internal and external wall insulation materials, such as polystyrene and extruded board, have extremely poor safety and stability, are easy to fall off and cause fire, and Class B materials are flammable, burning fast, and not environmentally friendly. Serious pollution of the environment during the production process. At the same time, the design life of polystyrene, extruded board and phenolic board for exterior wall is generally about 15 years. Because of its nature, it is difficult to recycle organic materials. Once it falls off or the construction life is terminated, a large number of buildings will be created during the second construction. Garbage can cause great pollution to air, water and natural environment. In recent years, building insulation materials that are both energy-saving and fire-proof have gradually become a new hot spot in the construction industry.
