Cold-Climate Window Tips

  • 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% to 50%. Storm windows should have weather-stripping 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.
