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. Since ENERGY STAR focuses on saving energy, you’ll likely also save on your energy expenses. All Pella windows and doors meet or exceed ENERGY STAR certification in all 50 states. How does this benefit you? Not only might you experience a decrease in your heating and cooling costs, you’ll also help support the environment. Furthermore, you’ll add to 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 treatments, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you peruse through our site or Charlotte Showroom. It’ll be located on the product’s NFRC label. Some Pella products greatly exceed U.S. ENERGY STAR guidelines. Contact your Charlotte Showroom to learn more. Schedule Now!
