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 efforts. Since ENERGY STAR focuses on conserving energy, you’ll likely also save on your energy expenses. All Pella windows and doors 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 support the environment. And, you’ll enhance your home’s comfort since our ENERGY STAR certified products block most 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 peruse through our site or Annapolis Showroom. You’ll find it located on the product’s NFRC label. Some Pella products greatly exceed U.S. ENERGY STAR guidelines. Contact your Annapolis Showroom to learn more. Schedule Now!
