浅谈如何提高PVC—U塑料窗的保温性能

塑料窗作为建筑物的外围护结构之一，直接影响到建筑物的节能性能，提高窗体的保温性能是降低建筑物能耗的主要途径。可通过优化框型材材性和断面设计、降低玻璃的传热系数、提高塑料窗气密性和设计合理的窗框比来提高PVC—U塑料窗的保温性能。

How to improve thermal insulation of PVC-U steel windows

As the one of the external retaining structure of the building, PVC-U window directly impact the energy-saving performance of buildings. So improving the insulation of windows is the main way to reduce energy consumption of building. There are some measures, such as optimizing wood frame profiles and cross-section design, reducing the heat transfer coefficient of glass, improving air tightness and designing the Proportion of the window and frame, and so on.
