Crafted by Pella, Certified by ENERGY STAR® ENERGY STAR is a program created by the U.S. Environmental Protection Agency and the U.S. Department of Energy to help Americans shield the environment through energy efficient products and activities. Since ENERGY STAR focuses on saving energy, you’ll likely also save on your energy costs. All Pella glass options meet or exceed ENERGY STAR certification across the U.S. How does this impact you? Not only might you see lower heating and cooling costs, you’ll also help take care of the environment. Moreover, you’ll help increase your home’s comfort since our ENERGY STAR certified glass blocks a majority of the sun’s ultraviolet rays. That means almost no fading for your window shades, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you browse through our site or Concord Showroom. It’ll be located on the product’s NFRC label. Some Pella products considerably exceed U.S. ENERGY STAR guidelines. Contact your Concord Showroom to learn more. Schedule Now!
