(1) the scope of application is wide:

外保温不仅适用于北方需冬季保温地区的采暖建筑，也适用于南方需夏季隔热地区的空调建筑;既适用于新建建筑，也适用于既有建筑的节能改造。

The external thermal insulation is not only suitable for heating buildings in winter, but also for air conditioning buildings in the south which need heat insulation in summer. It is suitable for new buildings as well as energy efficient retrofit for existing buildings.

(2)保温效果明显 ：

(2) the effect of heat preservation is obvious:

由于保温材料置于建筑物外墙的外侧，基本上可以消除在建筑物各个部位的“热桥”影响。 从而充分发挥了轻质高效保温材料的效能，相对于外墙内保温和夹心保温墙体，它可使用无机纤维喷涂保温材料，达到较高的节能效果。

Because of the outside insulation materials in buildings, basically can be eliminated in all parts of the building thermal bridge effect. So as to give full play to the effectiveness of lightweight and efficient thermal insulation materials, it can use inorganic fiber spraying thermal insulation materials to achieve higher energy saving effect compared with external wall insulation and sandwich insulation wall.

(3)保护主体结构：

(3) protection of the structure of the subject:

置于建筑物外侧的保温层，大大减少了自然界温度、湿度、紫外线等对主体结构的影响。随着建筑物层数的增加。温度对建筑竖向的影响已引起关注。国外的研究资料表明，由于温度对结构的影响，建筑物竖向的热胀冷缩可能引起建筑物内部一些非结构构件的开裂，外墙采用外保温技术可以降低温度在结构内部产生的应力。

The insulation layer on the outside of the building greatly reduces the influence of natural temperature, humidity and ultraviolet light on the structure of the main body. As the number of buildings increased. The effect of temperature on the vertical structure of the building has attracted much attention. Foreign research data show that due to the influence of temperature on structure, the vertical thermal expansion and contraction of buildings may cause cracks in some non structural components of buildings. The external wall insulation technology can reduce the stress generated by temperature inside the structure.
