外墙系统的老化表现及寿命在很大程度上受制于其湿热负荷,除了温度、日照和空气湿度等气候条件以外,影响外墙的因素往往还有来自外部或内部的潮湿源,如风夹雨、建筑材料自身的潮湿或表面结露。由于外墙外保温系统的体积较小,因而受到这些因素的影响尤大。但是,对那些使用了外墙外保温系统的建筑物的长期研究结果表明,外墙外保温系统并非比其他种类的墙体更脆弱。除了外观上的一些缺陷外,我们对外墙外保温系统耐 Exterior system aging performance and life expectancy is largely subject to its hot and humid load, in addition to temperature, sunlight and air humidity and other weather conditions, factors affecting the external walls often have external or internal sources of moisture, such as the folder Rain, building materials themselves wet or surface condensation. Due to the small size of the exterior insulation system, which are particularly affected by these factors. However, long-term findings for buildings that use exterior insulation systems show that exterior insulation systems are not more vulnerable than other types of walls. In addition to some of the appearance of defects, we are resistant to external insulation system
