[MassHistPres] Window research

[Brandon Wilson]

Amen!  
 
This is exactly our experience here in Somerville, and we are finding that updating an old window resource sheet has become very challenging and time consuming, given all of the possible variables and window types and manufacturer representations to consider.   So if anyone does have access to such a summary, written so that it can be used as a hand-out to homeowners, or can draft one, please let us know.
 
Sincerely,
J. Brandon Wilson

It would be really helpful if an organization that has some credibility would take the various window studies that have been done and summarize them into a position that replacement windows are not the panacea that the window companies and renovators make them out to be.

Without such a credible supporter, we are all on our own when it comes to refuting a fairly large machine who's goal is to get everyone into the replacement window space. Even if a local historic commission puts together such a study, it can be very easily dismissed as just a bunch of cranks trying to stop progress.

The level of hysteria seems to be rising; we have homeowners who believe that old wooden windows are as good as having empty holes in their building, and that without replacements, they may not survive in their domiciles over the winter.
