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 shield the environment through energy efficient products and efforts. Because 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 in every state. What does this mean for you? Not only might you experience decreased heating and cooling costs, you’ll also help take care of the environment. Moreover, you’ll add to your home’s comfort since our ENERGY STAR certified products block a majority of the sun’s ultraviolet rays. That means virtually 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 Gaithersburg Showroom. You’ll find it located on the product’s NFRC label. Some of Pella’s products considerably exceed U.S. ENERGY STAR guidelines. Contact your Gaithersburg Showroom to learn more. Schedule Now!
