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 shield the environment through energy efficient products and activities. Because ENERGY STAR focuses on conserving 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 impact you? Not only might you experience lower heating and cooling costs, you’ll also help take care of the environment. Moreover, you’ll add to your home’s comfort since our ENERGY STAR certified glass blocks most of the sun’s ultraviolet rays. That means little to no fading for your window treatments, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you peruse through our site or Washington DC Showroom. You’ll find it located on the product’s NFRC label. Some Pella products significantly exceed U.S. ENERGY STAR guidelines. Contact your Washington DC Showroom to learn more. Schedule Now!
