Install Storm Windows

A large amount of heat can be lost through single-pane windows in the winter, resulting in energy waste. A simple solution is to install storm windows. Note: If the primary windows are in need of replacement, then energy-efficient replacement windows should be considered as an alternative to storm windows.The purpose of storm windows is to save energy and to increase comfort. Storm windows save energy in two ways. First, they reduce air leakage through spaces around the window. Second, they reduce heat conduction through the window by creating an insulating air space between them and the primary window. In addition to saving on heating costs in the winter, storm windows can save on cooling costs in the summer.

Beyond saving energy, storm windows enhance the comfort of the residents, lower maintenance costs on existing windows, and reduce the amount of outside noise and pollutants that enter the dwelling unit.

Performance/Economics

• Storm windows can save up to 10 percent on heating costs.
• The cost-effectiveness of this measure depends on the quality of the existing windows, the cost and type of storm window, current energy costs, and climate.
