Energy loss through old windows and doors is significant. Heat and cold can escape from poorly sealed windows, cracked door frames, or windows and doors that don’t open and close properly or seal tightly. Condensation can form between panes on non-sealed glazing window or storm windows. Additionally, moist air that has leaked past inner window panes can create condensed on outer window panes. Even dry areas can suffer from condensation problems if the windows and doors are not sealed to the interior space.
