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 preserving energy, you’ll likely also save on your energy costs. All Pella glass options meet or exceed ENERGY STAR certification in all 50 states. What does this mean for you? Not only might you experience decreased heating and cooling costs, you’ll also help support the environment. Moreover, 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 almost no fading for your window coverings, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you browse through our site or Hunt Valley 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 Hunt Valley Showroom to learn more. Schedule Now!
