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 in every state. How does this impact you? Not only might you experience lower heating and cooling costs, you’ll also help support the environment. And, you’ll add to 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 coverings, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you browse through our site or Birmingham Showroom. You’ll find it located on the product’s NFRC label. Some of our products considerably exceed U.S. ENERGY STAR guidelines. Contact your Birmingham Showroom to learn more. Schedule Now!
