      Nonflammable building exterior wall insulation board in the end, what does?
      "Now wall insulation material on the market can be divided into two categories: plastic plate polystyrene board and its agents flammability level can be divided into:. A-level (non-combustible), B1 (flame retardant), B2 (flammable), B3 (combustible) four fire levels. benzene board combustion class B1, such a low price sheet, many developers use the B1 level or even inferior benzene board to do the cell wall insulation materials, led to a fire accident at the time of external wall insulation It has occurred.
           According to the survey: In recent years, the province outer wall insulation material applied gradually combustibility as A grade material, such as external wall insulation; phenolic foam, RGC lightweight wall panels, light fire partition board, these walls materials can effectively avoid cross dripping construction work welding sparks ignited insulation material fire occurred. According to state regulations for new building materials, refractory at 1000 ° C reached four hours of non-combustible materials are qualified state Class A fire retardant materials. It is understood that, at present, China right light partition board Ltd. developed the production of light fire partition board, calcium silicate board panel, the core material is a mixture of polystyrene particles, special cement, etc., at 1000 degrees Celsius 4 hours fire resistance, fire resistance of the national a very standard, but do not emit any toxic gases in full compliance with international environmental standards; plastering can be made without the use of a container filled with water, without the slightest leakage. If large-scale use of such plates can either play a security role in environmental protection, energy efficiency without losing insulation, to achieve "double insurance" effect. And new types of building materials is not only good insulating effect, and thickness than ordinary thin insulation board a lot of countries have introduced policies, A grade fireproof materials will become the mainstream of China's construction industry, external wall insulation works.
