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 protect 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 see a decrease in your heating and cooling costs, you’ll also help support 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 little to no fading for your window treatments, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you browse through our site or Calgary Showroom. You’ll find it located on the product’s NFRC label. Some of our products considerably exceed U.S. ENERGY STAR guidelines. Contact your Calgary Showroom to learn more. Schedule Now!
