Crafted by Pella, Certified by ENERGY STAR® ENERGY STAR is a joint program of 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 expenses. All Pella windows and doors 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 products block a large percentage of the sun’s ultraviolet rays. That means virtually 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 Shrewsbury Showroom. The logo will be located on the product’s NFRC label. Some Pella products greatly exceed U.S. ENERGY STAR guidelines. Contact your Shrewsbury Showroom to learn more. Schedule Now!
