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 protect the environment through energy efficient products and activities. Since ENERGY STAR focuses on conserving energy, you’ll likely also save on your energy bill. All Pella products meet or exceed ENERGY STAR certification in all 50 states. How does this benefit you? Not only might you find lower heating and cooling costs, you’ll also help protect the environment. Moreover, you’ll add to your home’s comfort since our ENERGY STAR certified glass blocks a large percentage of the sun’s ultraviolet rays. That means little to no fading for your window treatments, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you glance through our site or Wilmington Showroom. You’ll find it located on the product’s NFRC label. Some Pella products greatly exceed U.S. ENERGY STAR guidelines. Contact your Wilmington Showroom to learn more. Schedule Now!
