Window Replacement Options

Whether you would like to explore window replacement options to improve the energy performance of your existing windows or replace them with new energy-efficient windows, several options are available. An energy audit can help you identify promising strategies for more efficient windows and a more efficient house. Whichever energy efficiency measures you consider, the federal government, as well as state, local, and utility programs, may offer financing help or weatherization assistance.

While most new windows have labels indicating their energy properties, such information is not often available for existing windows.
