高性能建筑外窗耐候性试验研究及性能影响分析

Experimental study on weatherability of high performance exterior windows buildings and analysis on performance influence

门窗是建筑围护结构的重要组成部分,门窗耐候性能直接影响外窗的性能,从而影响建筑的整体节能性能。在介绍耐候性评价方法和设备基础上,研究耐候性试验方案,并对研发的高性能PVC-U塑料节能窗进行耐候性试验,分析耐候性试验前后节能窗的性能,分析影响外窗耐候性能的原因,并提出改进方法。

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.
