The cost of energy-efficient windows can vary widely depending on various factors such as the brand, materials used, features, and the size of the windows. Generally, you can expect to pay more for windows with advanced features like triple-pane glass, low-emissivity (Low-E) coating, and argon gas filling, as you find in Champion Comfort 365 Windows®.
It's essential to consider that while the initial cost may be higher compared to standard windows, energy-efficient windows are an investment that can save you money in the long run through reduced energy bills. According to the U.S. Department of Energy, replacing old windows with Energy Star® certified windows can save you between $126 to $465 a year depending on your region and the number of windows you replace.
