Why buy ENERGY STAR?
• Installing ENERGY STAR-qualified windows lowers energy bills and saves you money over single-paned and even new double-paned, clear-glass windows. • ENERGY STAR-qualified windows protect from the winter cold and summer sun, while also reducing condensation and interior fading. They keep your home cooler in the summer and warmer in the winter, making you more comfortable. • Every ENERGY STAR-qualified window, door, and skylight is independently certified to perform at levels that meet or exceed strict energy efficiency guidelines set by the U.S. Department of Energy. ENERGY STAR® performance requirements are tailored to fit the energy needs of the country’s different climate regions – northern, southern and central states. Additionally, recent technological advancements — new materials, coatings, design and construction features — make it possible to choose window products that allow you to balance your winter heating and summer cooling needs without sacrificing versatility or style
