In the external area of the application technology, more than 15 walls can be built up on both sides with ETICS . During the outdoor weathering tests, coatings and structures of ETICS or other customary industrial structures are partially exposed for years to the weather conditions in Ober-Ramstadt in order to observe the reaction to the climatic stresses (freeze-thaw; wet-hot etc.). In addition, various research projects are exposed to outdoor exposure. With material manufacturers and researchers, projects such as the "rained façade" are set up and continuously monitored. If necessary, samples are taken and permanently checked on the basis of weather measurement data, sensors installed in the system and evaluated by the respective departments.
