If you’re dealing with poor window performance, such as drafty windows, temporary solutions like sealants and weatherstripping won’t keep your home comfortable for long. Replacement windows from Great Lakes Window will seal out unwanted cold and heat, saving you a bundle on heating and cooling costs. So while Mother Nature stays out, energy efficient windows keep you safe and sound all year-round. Our windows are built to resist the heat and cold, offering four-season comfort. Need proof? We meet or exceed the current standards for ENERGY STAR® Version 6.0 requirements in all 50 states and can exceed requirements for the Northern Zone, by up to 48% with select glass packages. Below are four common ratings that are provided for windows certified by the National Fenestration Rating Council (NFRC), the American National Standards Institute (ANSI) and the American Architectural Manufacturers Association (AAMA).
The Windows look great and we can see the a/c and heating savings already. We highly recommend this company.

In 2016, ENERGY STAR changed their ratings dictating what U-Values and Solar Heat Gain Coefficient ratings will be required in order to receive the ENERGY STAR for windows and sliding patio doors. To find out what these new ratings are, mouse over or click on your region to see the ENERGY STAR requirements for your region.
Because Great Lakes Window has ENERGY STAR windows, the National Fenestration Rating Council (NFRC) labels are printed on all Great Lakes windows.
The ENERGY STAR Most Efficient 2020 designation recognizes the most efficient products among those that qualify for the ENERGY STAR program. The Great Lakes Window ecoSmart, ComfortSmart and HarborLight windows represent the leading edge in energy efficient products this year.
