The external thermal insulation system is an insulation decoration system compounded on the outside of the structural wall. Its own combustion function and fire resistance limit are the first to resist the fire of the adjacent building. When considering the safety of external wall fire safety, first of all, we should consider the combustion function of the material itself, so the external thermal insulation material should be non-combustible or flame retardant. Today, China's thermal insulation materials are mostly high-molecular organic compounds. Despite the flame-retardant treatment, in the event of a fire, it will still cause combustion. The inorganic non-combustible heat preservation system has the advantages of good fireproof function, short construction period, non-toxicity and no pollution, and can be used as a substitute for the more popular organic thermal insulation materials.
