Government is working to reduce NDC (National Decisions Contribution) and greenhouse gas emissions. As a result, the construction industry is raising its annual carbon reduction target with the aim of contributing to Korea international greenhouse gas emissions. In this study, the wet-based Korea “ETICS” was evaluated in consideration of temperature and impact resistance according to the climate environment. The performance of the wet-based external insulation synthesis system was verified through experiment, and it is expected that the energy saving technology of Korean building will be further improved if the fire safety and insulation standard used in Korean building are met.
