U-factor connotes the flow of heat through a window Lower the U-factor better is the heat flow prevention into the room. In Virginia Beach, people look for 0.3 or less U-factor. Regarding air infiltration, look at the Air Infiltration rating below.


Solar Heat Gain Co-efficiency

Solar Heat Gain Co-efficiency or SHGC is the method for measuring the transmission of solar heat. If the SHGC is more than the specified norms then the solar heat inflow is more, through the glass panes, into the room. However, people who reside in a cold region, the SHGC ought to be higher and vice-versa for people staying in warm climate. In Virginia, tidewater zone people opt for U-factor .20 and .30.
