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. Because ENERGY STAR focuses on saving energy, you’ll likely also save on your energy expenses. All Pella glass options meet or exceed ENERGY STAR certification in every state. How does this impact you? Not only might you see decreased heating and cooling costs, you’ll also help take care of the environment. Furthermore, you’ll help increase your home’s comfort since our ENERGY STAR certified products block a large percentage of the sun’s ultraviolet rays. That means little to 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 Roanoke Showroom. You’ll find it located on the product’s NFRC label. Some of Pella’s products significantly exceed U.S. ENERGY STAR guidelines. Contact your Roanoke Showroom to learn more. Schedule Now!
