Abstract
More than 500 million m2 of External Thermal Insulation Composite Systems (ETICS) have been employed 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 performance and the weather resistance of façades 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 façades 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.
