Replacing windows is rarely cost-effective based solely on energy-savings. However, if you are planning to replace your windows, doors or skylights because of maintenance or aesthetic reasons, make the most of the opportunity and consider ENERGY STAR labeled products. They save you energy and money, increase the comfort of your home, prevent condensation and protect your valuable possessions from sun damage. They are also better for the environment because lowering your energy use means less air pollution from power plants.
ENERGY STAR labeled windows, doors and skylights are twice as efficient as the average windows manufactured just 10 years ago. They help cut your heating and cooling costs and can make your home more comfortable without compromising cost, comfort, versatility or style. These high-performing windows are available in every operator type, including single- and double-hung, casement, horizontal slider, fixed, picture and patio slider. And they are manufactured with most common frame materials, including aluminum, fiberglass, vinyl and wood.
