The misting of windows is usually a sign of a failed treatment of the glass in the factory. The factory will put a low-emissivity coating on the window to reflect heat. It could also inject argon for extra insulation. If these treatments fail, moisture can get into the space between the glass panes and cause condensation. This issue can be resolved by a professional who drills tiny holes through the glass panes and then pipeing in a dehydrating solution to eliminate the moisture.
