Even the good standard vinyl windows(not include frame) themselves, should be very expensive. I bought from the builder supply and double panels are around $400-$500. Plus the frame and labor, should be 1K+. The 水蒸汽 is possible, but most of time is called low-e failure.

homedepot 的 american craftsman 窗户,tax credit eligible ~150-200 一个,很便宜。 节能效果咋样?
加安装恐怕也基本上$400/window了,不要找hd安装,that's the bottom line 能符合标准的应该就不错,也没有其他办法可以知道到底节能多少了。

都是tax credit eligible的窗户, U factor <=0.30 SHGC <=0.30 还有哪些因素影响节能效果啊?

上次发过,仅供参考。 窗子质量和价格差别比较大。北方冬天冷,对保暖要求高,可以考虑好一些的窗子。南 方也许更能将就一些,便宜点的窗子也能用。 窗子框架:个人不喜欢木头的,夏天开窗担心雨水,冬天担心冰和雾水。很容易腐烂, 换窗子很花钱。价格适中的可选vinyl材料(比如Fiberglass Composite就更贵)。The measurement of the efficiency of the frame material is called an R-factor. With the R-factor, the larger the number the more insulated the material. Foam-filled vinyl or multi-channel vinyl are good choice. Should consider R- factor > 4.0. 质量好的在vinyl中加一条金属框架增加强度。 新的设计窗子关回来和窗框密合处是阶梯形(3个台阶),这样更容易密封不透气。大 窗子过去一般有上下两个锁扣,先锁一个,然后再锁另一个。缺点是用力不
