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 support the environment through energy efficient products and practices. Since ENERGY STAR focuses on conserving energy, you’ll likely also save on your energy bill. All Pella glass options meet or exceed ENERGY STAR certification in every state. What does this mean for you? Not only might you experience a decrease in your heating and cooling costs, you’ll also help support the environment. Furthermore, you’ll add to 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 coverings, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you peruse through our site or Overland Park Showroom. The logo will be located on the product’s NFRC label. Some Pella products greatly exceed U.S. ENERGY STAR guidelines. Contact your Overland Park Showroom to learn more. Schedule Now!
