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 support the environment through energy efficient products and practices. Since ENERGY STAR focuses on preserving energy, you’ll likely also save on your energy bill. All Pella glass options meet or exceed ENERGY STAR certification in all 50 states. How does this impact you? Not only might you experience lower heating and cooling costs, you’ll also help protect the environment. Furthermore, you’ll enhance your home’s comfort since our ENERGY STAR certified glass blocks 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 Mt. Pleasant Showroom. The logo will be located on the product’s NFRC label. Some of Pella’s products greatly exceed U.S. ENERGY STAR guidelines. Contact your Mt. Pleasant Showroom to learn more. Schedule Now!
