IS THE “GREENER OPTION” OF REPAIRING HISTORIC WOOD WINDOWS BETTER THAN REPLACING THEM?

The National Trust for Historic Preservation has a new Tip Sheet entitled “Historic Wood Windows.”  Preservationists point out the replacements erode the character of a building, waste a historic resource and there is a potential net energy conservation loss.  Vinyl, aluminum or a composite of wood will not last as long as the original window.

The Tip Sheet explains why retaining wood windows is more cost and energy efficient than modern replacements.  Modern replacements often have a 20-year life whereas wood windows can be repaired to function indefinitely.  Energy savings will not recoup the expense of new windows within the 20 year life. Included is information on maintenance, lead paint concerns and resources for more information.
