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 practices. Since ENERGY STAR focuses on conserving energy, you’ll likely also save on your energy costs. All Pella products meet or exceed ENERGY STAR certification in every state. 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. Moreover, you’ll add to your home’s comfort since our ENERGY STAR certified glass blocks most of the sun’s ultraviolet rays. That means little to 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 Saint Louis Showroom. The logo will be located on the product’s NFRC label. Some of Pella’s products considerably exceed U.S. ENERGY STAR guidelines. Contact your Saint Louis Showroom to learn more. Schedule Now!
