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 support the environment through energy efficient products and efforts. Since ENERGY STAR focuses on saving energy, you’ll likely also save on your energy bill. All Pella glass options meet or exceed ENERGY STAR certification in every state. How does this impact you? Not only might you find lower heating and cooling costs, you’ll also help support the environment. Moreover, you’ll enhance 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 glance through our site or South Portland Showroom. You’ll find it located on the product’s NFRC label. Some Pella products significantly exceed U.S. ENERGY STAR guidelines. Contact your South Portland Showroom to learn more. Schedule Now!
