Energy Efficient Windows and Glazing Information

Before you peel that NFRC sticker off the window, check the numbers and ask whether you got the right window with the best SHGC for your climate.


For homeowners in Denver looking at new windows there are some things to consider.  One of them being the SHGC of a window.  Solar heat gain can provide free heat in the winter but can also lead to overheating in the summer. How to best balance solar heat gain with an appropriate SHGC depends upon the climate, orientation, shading conditions and other factors.
