In the early 1990s, China began to implement the internal wall thermal insulation technology for a long time. Its low cost, convenient construction and relatively mature technology, but there are many shortcomings, such as reducing the use of households; The problem of "heat bridge" is not easy to solve; it is prone to condensation, and the thermal insulation effect is poor; it is prone to cracking of the inner insulation surface layer; affecting the secondary decoration of the household; the damage to the insulation layer during the decoration process is large, resulting in a new round Construction waste; real estate developers could have been used as a selling point, often without the support of the residents; not conducive to the energy-saving transformation of existing buildings. Therefore, its applicability has been gradually replaced by external thermal insulation in recent years. In developed countries abroad, the external wall insulation technology has been applied for more than 60 years. After years of practice, it has been proved that the building with the insulation system has a longer service life; the life cycle cost is reduced; the same can be adopted for various external decoration effects; The appearance of cracks and water seepage on the external wall; the energy-saving effect of heat insulation is obviously better than that of internal heat preservation; the thermal insulation material is saved by about 40%, and the comprehensive economic benefit is remarkable. It is a kind of active and active external thermal insulation technology, and has wide application range.
