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 preserving energy, you’ll likely also save on your energy costs. All Pella glass options meet or exceed ENERGY STAR certification across the U.S. What does this mean for you? Not only might you experience a decrease in your 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 most of the sun’s ultraviolet rays. That means virtually no fading for your window treatments, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you browse through our site or Des Moines Showroom. The logo will be located on the product’s NFRC label. Some Pella products considerably exceed U.S. ENERGY STAR guidelines. Contact your Des Moines Showroom to learn more. Schedule Now!
