Composite fireproof glass, external wall insulation is the primary part of external thermal insulation. It is difficult to deal with the thermal bridge insulation of the internal insulation, which is prone to condensation, occupies the use area, affects the secondary decoration of residents, and the hanging and fixed objects of the internal wall also slightly damage the internal insulation structure, while the external insulation of the external wall is to fix a layer of insulation material on the outside of the main wall structure under the action of bonding materials, The outer side of the thermal insulation material shall be reinforced with glass fiber mesh and coated with adhesive mortar. The existing energy-saving projects are basically external wall insulation. It mainly uses bonding mortar or special fasteners to paste and hang thermal insulation materials on the outer wall, then plaster anti crack mortar, press into glass fiber mesh cloth to form a protective layer, and finally add decorative surface. Another method is to use special fixings to fix various thermal insulation boards that are not easy to absorb water on the outer wall, and then hang aluminum plates, natural stones, colored glass, etc. on the prefabricated keel to directly form the decorative surface.

Building energy conservation is the primary content of the implementation of the national environmental protection and energy conservation policy, and it is the primary component of the sustainable development strategy of the national economy. With the energy-saving standard increased from 30% of the original to 50%, the external wall insulation technology has been developed by leaps and bounds, and has become a primary building energy-saving technology in China. However, in recent years, fires of exterior wall insulation materials have occurred frequently, resulting in severe casualties and property losses. Therefore, with the full promotion of building energy conservation, the fire prevention question of building energy conservation is becoming more and more serious.
