High vs low u factor
WebBuy windows with a very low U-factor ( the lower the best, in all climates ). A U-factor of 0.35 (required by the Energy Star program for cold climates) is reasonable but not excellent. The best double-glazed windows have a U-factor of about 0.27 (whole-window value), while high-performance triple-glazed windows have a U-factor around 0.17. WebU-factor – A measure of the insulating power of a window. The lower the number the more the window will insulate. Therefore, a window with a low U-factor is better for cold …
