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 support the environment through energy efficient products and activities. Because ENERGY STAR focuses on conserving energy, you’ll likely also save on your energy costs. All Pella glass options meet or exceed ENERGY STAR certification in every state. How does this impact you? Not only might you see a decrease in your heating and cooling costs, you’ll also help protect the environment. And, you’ll add to your home’s comfort since our ENERGY STAR certified glass blocks a large percentage 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 glance through our site or Woburn Showroom. It’ll be located on the product’s NFRC label. Some Pella products significantly exceed U.S. ENERGY STAR guidelines. Contact your Woburn Showroom to learn more. Schedule Now!
