Exterior wall insulation is an insulation method which the insulation layer is placed outside the main wall. Because it could reduce the influence of cold bridge at the same time protect the main wall free from the tempreature deformation stress which is the inslution method commonly used in China. The paper analyzed the exterior insulation system's development prospect at construction energy saving field and the advantages and disadvantages at construction process, the development idea of exterior inslution construction technology is proposed.%外墙外保温是一种把保温层放置在主体墙材外面的保温做法,因其可以减轻冷桥的影响,同时保护主体墙材不受多大的温度变形应力,是目前国家大力倡导的保温做法.本文针对分析外墙外保温系统在现阶段建筑节能领域的前景,以及此工艺在施工时的优点和缺点,对外墙外保温施工技术的提出发展思路.
