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 efforts. Because 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 in every state. How does this benefit you? Not only might you experience lower heating and cooling costs, you’ll also help protect the environment. And, you’ll help increase your home’s comfort since our ENERGY STAR certified products block most 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 Burlington 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 South Burlington Showroom to learn more. Schedule Now!
