Cold-Climate Windows
Double-pane windows with low-e coating on the glass reflect heat back into the room during the winter months.
- Install exterior or interior storm windows; storm windows can reduce your heat loss through the windows by 25 percent to 50 percent. Storm windows should have weatherstripping at all moveable joints; be made of strong, durable materials; and have interlocking or overlapping joints. Low-e storm windows save even more energy.
- Repair and weatherize your current storm windows, if necessary.
- Install tight-fitting, insulating window shades on windows that feel drafty after weatherizing.
- Close your curtains and shades at night; open them during the day.
- Keep windows on the south side of your house clean to maximize solar gain.
