If you live in an older home, there’s a good chance its windows are made from single panes of glass. Newer homes typically come with double-pane windows, and for good reason: They’re far more energy-efficient. In fact, the U.S. Department of Energy estimates that you can save 7%–15% on heating and cooling bills when you replace single-pane windows with double-pane versions.
You can find out how much money a window swap could save you by visiting the Energy Star website, energystar.gov. For Texans, savings average $230 per year. Be sure to compare the savings with the cost and expected life of the windows to determine if it’s a good investment.
If new windows aren’t in the budget, there are still some solutions to make your single pane windows more efficient.
- Check for air leaks and apply caulk or install weatherstripping.
- Put up energy-efficient window treatments like blinds or curtains.
- Install window film and hang exterior shades such as awnings to reduce solar heat gain in warmer months.
