How Your Windows and Doors Cause Heat Gain and Loss

Windows, doors, and skylights can gain and lose heat through direct conduction through:

The glass or glazing, frame, and/or door glass.
The radiation of heat into a house (typically from the sun) and out of a house from room-temperature objects, such as people, furniture, and interior walls.
Air leakage through and around windows and doors.
