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 efforts. Because ENERGY STAR focuses on preserving 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 see lower 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 glass blocks most 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 glance through our site or Hanover Showroom. It’ll be located on the product’s NFRC label. Some of our products greatly exceed U.S. ENERGY STAR guidelines. Contact your Hanover Showroom to learn more. Schedule Now!
