Our energy saver calculator is intended solely to guide the consumer when selecting a type of window product.

Our energy saver calculator has been developed from a heating and cooling calculator software created for residential buildings. It also relies on U.S. and Canadian certified energy efficiency data.

The results should be used as an indication only and might differ from the reality. In fact, many factors might influence the true results such as the actual condition of the home, the weather and the relative air humidity as well as the quality of the replacement window’s installation. The manufacturer’s choice of window glazing can also affect the results.

Atlantic Windows do not guarantee the accuracy of the energy savings estimated by the calculator.
