You can improve the energy efficiency of existing windows by doing the following:

  • Adding storm windows

    Reduce air leakage and some heat transfer

  • Caulking and weather stripping

    Reduce air leakage around windows

  • Using window treatments or coverings

    Reduce heat loss and/or gain

However, if your home has very old and/or inefficient windows, it might be more cost effective to replace them than to make these improvements. New, energy-efficient windows eventually pay for themselves through lower heating and cooling costs, and sometimes even lighting costs.
