摘　　要：自1960年代以来,在德国已有超过5亿平米外保温系统用于建筑物保温。在近十年中外保温的使用变成了改善节能性能和外立面耐候性的一种流行的措施。这也自然引起了关于外保温系统相对于其他保温形式的耐久性的种种疑问。因此,自1975年以来,佛朗霍夫建筑物理研究所对一大批做了外保温的多层住宅进行了数次检查。这些重复检查的结果可以归纳如下:外保温系统表面的破坏或退化并不比普通的表面抹灰的砖石结构墙体更常见。检查发现,外保温系统由于雨水或外表面结露而滋生微生物的情况稍微多一些。外保温系统的维修费用和维修周期与普通墙体相当。其他方面的耐久性也是如此。More than 500 million m2 of External Thermal Insulation Composite Systems （ETICS） have been applied to insulate buildings in Germany since the early 1960s, In the last decade the application of ETICS became a popular measure to improve the energy saving performance and the weather resistance of facades in the building stock, Naturally this raises questions about the durability of ETICS compared to other types of thermal insulation, Therefore a substantial number of multi-storey houses with ETICS have been inspected several times since 1975 by the Fraunhofer Institute for Building Physics, The results of these repeated inspections may be summarized as follows： Damage or degradation of ETICS facades are no more frequent than with conventional rendered masonry walls, A slightly greater susceptibility of ETICS to microbial growth due to rain or condensation water can be detected, Costs and frequency of maintenance for ETICS are comparable to those of traditional wall structures, The same holds for other durability aspects.
