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 shield the environment through energy efficient products and activities. Since ENERGY STAR focuses on preserving energy, you’ll likely also save on your energy expenses. All Pella products meet or exceed ENERGY STAR certification across the U.S. How does this benefit you? Not only might you find decreased heating and cooling costs, you’ll also help protect the environment. And, you’ll help increase 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 coverings, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you browse through our site or Raleigh Showroom. The logo will be located on the product’s NFRC label. Some Pella products considerably exceed U.S. ENERGY STAR guidelines. Contact your Raleigh Showroom to learn more. Schedule Now!
