Double-pane windows are a popular choice for energy efficiency, but their lifespan can vary based on factors like climate, installation quality, and maintenance. Typically, you can expect them to last anywhere from 15 to 30 years. However, issues such as seal failure can lead to condensation between panes, affecting performance. It's essential to consider the materials used, potential energy savings, and the cost of replacement versus repair.
