In the use of asbestos sheet, to ensure that the insulation effect at the same time to pay attention to whether the fire performance standards, in addition, but also to do in the fire can help save energy, can not be afraid of the occurrence of fire, and pay attention to fire, but ignored the important principle of energy saving. The inorganic insulation material is also represented by rock wool and foam glass. The thermal conductivity of rock wool and slag cotton at room temperature (around 25 ℃) is usually in 0.036~0.041w/(m. K), which itself belongs to the inorganic silicate fiber, nonflammable. Rock wool with a Class A fire, heat insulation and other characteristics, is designed for the external wall of the building outside the thin plastering system design, production, the use of the base wall for concrete or brick walls and other dense structure of the new or existing building external wall insulation or energy-saving transformation, but also can be used to do external wall insulation fire isolation zone,
And the combustion performance is not up to a-grade insulation materials supporting the use, in order to improve the building exterior wall fire protection function. Exterior wall insulation materials should combine the four disciplines of architecture science, material science, fire science and environmental science. Any study deviating from the four disciplines has relative unilateralism and limitation.
It is necessary to do the following points to do the fire protection of exterior wall insulation:
1) Strict implementation of various fire protection regulations and fire protection system;
2) Choose a good insulation material;
3) The use of insulation materials in the initial stage to do fire prevention measures;
4) The use of insulation materials in the intermediate stage to do a good job in monitoring the construction process to prevent the possibility of various fires; 5) After the insulation material made of external wall insulation system, good insulation system after the correct use and prevent the occurrence of fire.
