摘要
建筑外窗作为建筑围护结构中的轻质、薄壁构件,其能耗往往占到整个建筑能耗的三分之一左右。实际工程应用中外窗保温性能不仅受制作材料影响,受气密性能影响也很大。根据近几年国家对节约能源走可持续发展的要求,建筑外窗保温的检测、评判应面向实际应用。
As light thin component witch guard ring the buildings,external windows consume about a third of total energy.Thermal insulating properties of external windows are not only affected by it s material,but also affected by air permeability performance.For the desire of continuance in recent years,the test methods and judging of external windows may face to practicality.
