Recently, the system construction technologies are developed and used in construction sites, such as the technology to attach the insulation material to the concrete base surface and the introduction of dry process, to remove the elements of ruptures such as the quality deterioration of the mortar paste, abnormal climates, heavy rain, and strong winds. Even with such technology developments, the quality management standard is still not specified in Korea to measure the adhesion strength of the fixed exterior finishing panel and to verify the strength of the junction between insulation materials. The performance of the exterior panel was verified through the performance test for the wall fixing anchor of the exterior panel and Mock-up test in this study. This seems to be able to be applied to higher building parts. This study is intended to derive the development as the process to solve the problems of the existing exterior panels. Also, it demands the necessity of preparing test specifications for the performance test since there is no KS specification.
