外墙外保温是一项先进的外墙节能技术。但外墙外保温系统位于建筑物的外表面，直接面向大气环境。除系统性能应承受室外多种不利因素的作用和满足外墙外保温隔热要求外，其可靠性、完全性和耐久性尤为重要。
高层建筑外墙保温需要特别注意下列问题：
一、保温系统与基层墙体应有可靠的固定。高层建筑应承受风荷载较大，而且墙体部分会产生很大负风压（吸力）。因此，保温层应与基层（无机材料）有可靠的黏结，尤其是采用（有机材料）保温板，一定要注意这个环节。而由无机材料构成的保温层，与各种基层墙体（无机的混凝土、各类墙体材料等）具有良好的匹配性和相容性；同时受到风荷载作用下不会变形、剥落，具有高度的安全性和可靠性。
二、保温系统的防火性能应符合国家有关法律规定。现在高层建筑外墙保温较多采用阻燃性聚苯板，这类材料具有可燃性，用于高层建筑外墙保温应采取防火构造措施，如设置防火隔离带等。
三、外饰面层应采用涂料（或彩色砂浆）。保温系统中的保温层多为轻质多孔材料、剪力强度较低，所以饰面层不宜采用面砖。如黏贴面砖必须要有可靠的措施，以防止面砖脱落伤人。
四、保温系统的耐久性能应满足要求。在正常使用和维护条件下，外墙外保温工程的使用年限应不少于25年。
