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 shield the environment through energy efficient products and efforts. Since ENERGY STAR focuses on preserving energy, you’ll likely also save on your energy bill. All Pella glass options meet or exceed ENERGY STAR certification in all 50 states. How does this benefit you? Not only might you see lower heating and cooling costs, you’ll also help take care of 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 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 Monroe Showroom. It’ll be located on the product’s NFRC label. Some Pella products considerably exceed U.S. ENERGY STAR guidelines. Contact your Monroe Showroom to learn more. Schedule Now!
