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 support the environment through energy efficient products and activities. Because ENERGY STAR focuses on conserving energy, you’ll likely also save on your energy expenses. All Pella products 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 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 little to 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 Boston Showroom. It’ll be located on the product’s NFRC label. Some of our products considerably exceed U.S. ENERGY STAR guidelines. Contact your Boston Showroom to learn more. Schedule Now!
