What is the ENERGY STAR Windows Program?

Look for the ENERGY STAR

The ENERGY STAR Windows Program is a voluntary partnership between the U.S. Department of Energy and the fenestration industry to promote sales of energy efficient windows, doors and skylights. By choosing ENERGY STAR qualifying products, homeowners can cut their heating and cooling costs, help make their homes more comfortable and reduce air pollution without sacrificing versatility or style.

Manufacturers and Retailers agree to promote energy-efficient windows, doors and skylights through a Memorandum of Understanding signed with the U.S. Department of Energy.
