Triple-pane windows cost 15 to 40 percent more than double-pane windows, but they will pay for themselves over time. Window replacement experts have found that double-pane windows can help homeowners save up to 24 percent in cold climates and up to 18 percent in warmer climates in the summer months. Windows are typically rated by U-factor: the lower the U-factor, the more energy-efficient and expensive the windows are.

The most common window styles are single hung, double hung, casement, sliding, and basement. Size is not the final determination of cost, as the style of the window influences it as well. If you’re installing multiple windows, then the price can go up exponentially. Large windows generally cost more to install than smaller windows. If you’re located in a milder climate, double-pane windows are often the go-to for adequate insulation. They are more expensive than single- or double- pane windows, but they will work the best in a colder climate.

For example, if you live in an area with a cold climate, triple-pane windows offer the best protection and insulation against cold wind and storms. Total costs vary due to differences in installation, local climate, types of windows, and more. Calculating window prices can be difficult, as the costs of the various factors will differ.
