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 support the environment through energy efficient products and activities. Since ENERGY STAR focuses on saving energy, you’ll likely also save on your energy bill. All Pella windows and doors meet or exceed ENERGY STAR certification in all 50 states. How does this benefit you? Not only might you see lower heating and cooling costs, you’ll also help support the environment. Furthermore, you’ll enhance your home’s comfort since our ENERGY STAR certified products block a majority of the sun’s ultraviolet rays. That means virtually no fading for your window shades, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you browse through our site or Winston-Salem Showroom. You’ll find it located on the product’s NFRC label. Some Pella products significantly exceed U.S. ENERGY STAR guidelines. Contact your Winston-Salem Showroom to learn more. Schedule Now!
