[MassHistPres] Thermal Pane Windows

[Susan Bragdon]

A few years back I sent an e-mail request about thermal pane windows, and I
am looking to update this again.  
Does any Historic District allow thermal pane windows and, if so, is there a
determination ie, distance from street or window configuration.  Any
information is welcome.    
Thank you.
