Recently, the number of renovation with external thermal insulation for energy-saving has been increasing. This report shows four experimental studies on external thermal insulation system for apartment houses. First, based on noncombustible certification test, it was found that the system was composed of noncombustible materials. Second, as the result of test for tensile strength, the system turned out to have the durability to wind load and strain. Finally, strain test and exposure test were carried out. The result showed that strain was within the permissible range in the system through changes of temperatures and weather conditions.
