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.
