Crafted by Pella, Certified by ENERGY STAR® ENERGY STAR is a partnership between the U.S. Environmental Protection Agency and the U.S. Department of Energy to help Americans protect the environment through energy efficient products and practices. Since ENERGY STAR focuses on saving energy, you’ll likely also save on your energy expenses. All Pella products meet or exceed ENERGY STAR certification in every state. How does this impact you? Not only might you find lower heating and cooling costs, you’ll also help take care of the environment. Furthermore, you’ll add to your home’s comfort since our ENERGY STAR certified glass blocks most 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 Haverhill Showroom. You’ll find it located on the product’s NFRC label. Some Pella products greatly exceed U.S. ENERGY STAR guidelines. Contact your Haverhill Showroom to learn more. Schedule Now!
