WebDec 20, 2011 · Depending on your region of the country, such a window—if it’s Energy Star rated—has a U-factor (the rate of heat transfer and an indication of how well the window insulates) of 0.30 to 0.60 and a solar heat gain coefficient (which indicates how well the window blocks heat caused by sunlight) of 0.27 to 0.40. WebThe lower the U-Factor, the greater the resistance to heat flow. Doubled-Paned, or even Triple-paned windows will have lower U-Factors than single paned. Special gases, such as argon, are used between the panes to slow the thermal flow through the window and lower their U-Factor. High-efficiency windows can be costly, so it is helpful to have ...
