Recent scientific and field (not laboratory) studies prove that similar or better energy efficiency can be achieved by restoring, weatherizing and adding non-obstrusive storm windows. Old windows constructed 50-300 years ago were made of irreplaceable hardwood. This wood can be repaired; the glass panes reglazed; the chain or rope pulleys replaced; the full sashes tightly weatherized; and attractive storm windows installed on the interior or exterior. In addition to reducing the homeowner's heating bill, the aesthetic value of the old windows is maintained. Replacement and even newly-fabricated, look-alike wood windows will never preserve the authentic, historical and real estate value of original wood windows.
Third, we recently published the Window Preservation Standards I mentioned in March. These standards help remodeling contractors actually do this work. Last month you should have received a copy of the Window Preservation Standards from Bob Yapp, one of the Founders of the non-profit Window Preservation Standards Collaborative (WPSC).
Over 140 window restoration specialists, architects, state and local historic preservation and planning offices, DIYers, and builders collaborated to author these Standards. The Standards provide the much-needed information on how to restore old wood windows. Materials required, step-by-step instructions, and quality evaluation criteria are described in layperson language. Already 300 homeowners, local and state historic preservation offices, architects and now progressive remodelers are purchasing these standards to help set job and outcome requirements for contractors. I am the Chairperson of the WPSC Marketing Committee. Our goal is to propagate these standards across the world. The 300 copies sold through our website: http://www.windowstandards.org in our first month with no press releases or advertising is a testimony to the demand for such clear and concise information.
