摘　　要：泡沫玻璃外墙外保温系统已成为我国新型保温体系,是应用前景良好的绿色节能墙体产品。利用温度传感器,对嘉兴地区泡沫玻璃外墙外保温系统耐候性试验进行了实时监测与分析研究,对整个系统进行了墙体各层温度分布规律的研究。试验表明,泡沫玻璃外墙外保温系统由于泡沫玻璃保温层的隔热作用,界面层与保温层之间温度变化显著,存在的温差高达50℃,会造成较大的温度应力,对泡沫玻璃外墙外保温系统耐久性有一定影响。The external foam glass thermal insulating system on walls has become a new thermal insulation wall system in China＇s building wall,it is green energy-saving building wall product with good prospect and used for wall thermal insulation of building. In this paper,real-time monitoring with thermal sensor and analysis on temperature for external foam glass thermal insulating system on walls by weathering test in Jiaxing area,and study on temperature distribution for each layer of walls were conducted. The experiment showed that the temperature change between the interface layer and thermal insulation layer is significant due to the thermal insulation function of the foam glass insulation layer of the external foam glass thermal insulating system on walls,the temperature difference is up to 50 %,which can cause great temperature stress,and have certain effect on durability of the external foam glass thermal insulating system on walls.
