Abstract：Doors and windows are an important part of the building envelope，the weatherability of doors and windows can directly affect the performance of external windows，thus affecting the overall energy-saving performance of the building. Based on the weatherability evaluation method and equipment of the subject，this paper studies the weatherability test scheme，conducts the weatherability test on the high-performance plastic energy-saving window developed by the subject，analyzes the performance of the energy-saving window before and after the weatherability test，analyzes the reasons that affect the weatherability of the window，and proposes improvement methods.
Key words：building exterior windows，weatherability，test method，building energy efficiency
