Crafted by Pella, Certified by ENERGY STAR® ENERGY STAR is a partnership between the U.S. Environmental Protection Agency and the U.S. Department of Energy to help Americans protect the environment through energy efficient products and practices. 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 benefit you? Not only might you find decreased heating and cooling costs, you’ll also help take care of the environment. Furthermore, you’ll add to your home’s comfort since our ENERGY STAR certified glass blocks a majority of the sun’s ultraviolet rays. That means virtually 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 Peoria Showroom. It’ll be located on the product’s NFRC label. Some of Pella’s products greatly exceed U.S. ENERGY STAR guidelines. Contact your Peoria Showroom to learn more. Schedule Now!
