Andersen Advantage

Andersen is proud to be an ENERGY STAR® partner, offering energy efficient replacement windows and doors that help save on heating and cooling costs and create a comfortable home year-round. Our energy efficient windows and doors include High-Performance™ Low-E4® glass and optional High-Performance™ Low-E4® SmartSun™ glass, making it easy to save both money and energy.

We publish standard energy-efficiency performance ratings on all our products ratings that are consistently among the best in the industry. Homes with Andersen® windows and doors can dramatically help reduce their heating and cooling costs. These guidelines are based on the heat gain and loss of each product in various regions of the country.

ENERGY STAR®

ENERGY STAR is a joint program of the U.S. Environmental Protection Agency (EPA) and the Department of Energy that identifies and promotes energy efficient products in order to reduce carbon dioxide emissions. New ENERGY STAR qualified windows can help reduce your energy bill up to 15 percent. Estimated savings vary from region to region depending on current heating and cooling costs and are generally greatest where there are hot summers, cold winters or both. In addition, ENERGY STAR qualified windows and doors do more than just lower energy bills – they deliver more comfort, create less condensation, and protect your valuables from sun damage better than conventional clear-glass double-paned alternatives.

We’re pleased to say that the vast majority of Andersen windows and patio doors meet or exceed ENERGY STAR criteria throughout the United States. Visit energystar.gov to learn more about the ENERGY STAR Program.

National Fenestration Rating Council

The National Fenestration Rating Council® (NFRC) is a non-profit organization that provides fair, accurate and credible energy performance ratings for windows and doors. The best way to compare energy efficient windows and patio doors is to look at their NFRC labels.
