Keep more of your hard-earned money in your wallet by installing energy efficient storm windows. Not only are storm windows less expensive to install than replacement windows, they can also help you save up to 10% on your monthly heating and cooling costs by creating a thermal break between windows that reduces air movement.
You could save $26 per year, per window* for each storm window you add to your home and for a home with 15 storm windows, that can mean an energy savings of $390 per year. At that rate of return, the energy savings of a storm window will pay for itself in just 3.8 years compared to a payback time of over 30 years for double-pane thermal replacement windows.

Based on average 2008 industry pricing: $50 for a storm window, $450 for a double-pane thermal replacement window and $550 for low-e glass double-pane thermal replacement.
Storm windows make you feel more comfortable in your home, they help you lower your energy usage and you’ll be helping to keep the environment healthier—that’s a great return on investment.
