New Windows Will Pay For Themselves

I am a great fan of energy efficient construction, and have purchased some of the most efficient glazing systems for my home and cabin, but retro-fitting windows is a very expensive proposition, and unlikely to create an investment return equal to a passbook savings account rate.

  • Installing energy efficient windows in new construction has a much lower marginal cost and makes a lot of sense. (It is also most likely required by your local code).

  • Unlike cars, furnaces, and appliances, windows (and other insulation) can last for decades, and thus providing for long term energy savings.
  • Replacing those old windows has some other advantages: the new window will actually open and close; they may look better; they can help with soundproofing; and they will reduce interior convection currents. See the topic page on Preparing for Cold Weather.

    The bottom line: New windows may have all sorts of advantages but they are unlikely to "pay for themselves".
