Crafted by Pella, Certified by ENERGY STAR® ENERGY STAR is a joint program of 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. Because ENERGY STAR focuses on conserving energy, you’ll likely also save on your energy bill. All Pella glass options meet or exceed ENERGY STAR certification in all 50 states. What does this mean for you? Not only might you find lower heating and cooling costs, you’ll also help take care of the environment. Furthermore, 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 treatments, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you glance through our site or St. Paul Showroom. It’ll be located on the product’s NFRC label. Some of Pella’s products significantly exceed U.S. ENERGY STAR guidelines. Contact your St. Paul Showroom to learn more. Schedule Now!
