Weatherize Existing Windows for Increased Energy Efficiency

Weatherize Existing Windows for Increased Energy EfficiencyYour windows are one of the main causes of heat loss in the winter and heat gain in the summer. This means that they play a significant role in the cost of keeping your home comfortable. If you can afford it, you can replace your windows with more energy efficient ones; however, this isn’t always feasible. One of the best ways to keep your electricity costs down is to weatherize existing windows. Here are some of the ways that this can be done.

Fixes for Drafty Windows

  • Apply rope caulk – Old window sashes tend to shrink over time, which leaves spaces through which air can enter and escape. Rope caulk is soft and can be molded into the gaps. Rope caulk is also easy to remove.
  • Install V-seal weatherstripping – This plastic weatherstripping can be placed in the sides of sashes. V-seal weatherstripping won’t interfere with the opening and closing of your windows.
  • Attach shrink film – Shrink film is a clear plastic sheet that shrinks when heated. The heating is usually done with a hair dryer. The resulting film eliminates drafts and provides insulation.
  • Use insulated curtains – Insulated drapes can weatherize existing windows by preventing heat loss via convection and infiltration, as well as by conduction and radiation. Insulated curtains will usually consist of a decorative outer layer and a protective inner lining. Other elements include high-density foam, a reflective vapor barrier and a reflective film that helps to retain heat within the room.
