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 practices. Because 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. How does this impact you? Not only might you find decreased heating and cooling costs, you’ll also help support the environment. And, you’ll enhance 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 treatments, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you glance through our site or Beltsville Showroom. You’ll find it located on the product’s NFRC label. Some of Pella’s products greatly exceed U.S. ENERGY STAR guidelines. Contact your Beltsville Showroom to learn more. Schedule Now!
