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 activities. Because ENERGY STAR focuses on saving energy, you’ll likely also save on your energy costs. All Pella windows and doors meet or exceed ENERGY STAR certification in all 50 states. How does this impact you? Not only might you experience lower heating and cooling costs, you’ll also help take care of the environment. Moreover, you’ll help increase 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 shades, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you peruse through our site or San Antonio Showroom. You’ll find it located on the product’s NFRC label. Some of Pella’s products considerably exceed U.S. ENERGY STAR guidelines. Contact your San Antonio Showroom to learn more. Schedule Now!
