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 efforts. Since ENERGY STAR focuses on preserving energy, you’ll likely also save on your energy costs. All Pella products meet or exceed ENERGY STAR certification in every state. How does this benefit you? Not only might you see a decrease in your heating and cooling costs, you’ll also help support the environment. Furthermore, you’ll help increase your home’s comfort since our ENERGY STAR certified glass blocks most of the sun’s ultraviolet rays. That means almost 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 Lewes Showroom. It’ll be located on the product’s NFRC label. Some Pella products considerably exceed U.S. ENERGY STAR guidelines. Contact your Lewes Showroom to learn more. Schedule Now!
