Are energy-efficient windows worth the investment?
By Bob Millaway, South Jersey Community Expert & REALTOR®
Energy-efficient windows with double or triple panes, low-E coatings, and argon gas fill can reduce energy loss by 25 to 30 percent. However, they are expensive, with a typical payback period of 10 to 20 years. If your existing windows are single-pane or in poor condition, replacement is worthwhile. For newer windows in good condition, weatherstripping and caulking offer better value.
Why It Matters
Windows are a major investment. Understanding the payback period helps you decide whether to replace now or focus on lower-cost energy improvements first.
