Why Energy Efficiency Matters

Investing in energy-efficient windows is not just about reducing your carbon footprint; it also translates to tangible savings on your energy bills. According to the U.S. Department of Energy, replacing single-pane windows with ENERGY STAR® certified products can save homeowners up to $465 annually. The U-factor, which measures a window’s insulation value, is a critical factor in determining energy efficiency. The lower the U-factor, the better the window is at insulating your home.
