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 efforts. Since ENERGY STAR focuses on preserving energy, you’ll likely also save on your energy bill. All Pella products meet or exceed ENERGY STAR certification in all 50 states. What does this mean for you? Not only might you see lower heating and cooling costs, you’ll also help support the environment. And, you’ll enhance your home’s comfort since our ENERGY STAR certified products block a large percentage of the sun’s ultraviolet rays. That means virtually no fading for your window coverings, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you browse through our site or Oklahoma City Showroom. You’ll find it located on the product’s NFRC label. Some Pella products considerably exceed U.S. ENERGY STAR guidelines. Contact your Oklahoma City Showroom to learn more. Schedule Now!
