Crafted by Pella, Certified by ENERGY STAR® ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy to help Americans support the environment through energy efficient products and activities. Because ENERGY STAR focuses on saving energy, you’ll likely also save on your energy costs. All Pella products meet or exceed ENERGY STAR certification in all 50 states. How does this benefit you? Not only might you find decreased heating and cooling costs, you’ll also help take care of the environment. Furthermore, 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 coverings, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you glance through our site or Nashville Showroom. You’ll find it located on the product’s NFRC label. Some Pella products greatly exceed U.S. ENERGY STAR guidelines. Contact your Nashville Showroom to learn more. Schedule Now!
