I suspect that most of the existing glass is original to the wood sash and storms. The glass, which is likely somewhat wavy and figurative, is along with the sash, the window jambs, the trim and the storms themselves a significant character defining element of the building. <o:p></o:p></span></p><ol style='margin-top:0cm' start=1 type=1><li class=MsoListParagraph style='color:#030303;margin-left:0cm;mso-list:l0 level1 lfo1'><span style='font-size:9.5pt;font-family:"Arial",sans-serif;background:#F2F2F2'>Conserve the <em><span style='font-family:"Arial",sans-serif'>heritage value</span></em> of a historic place.

In addition, thermal glazed (double) units are of a significantly thicker depth and would require the storm window sash rebates to be routed out to accommodate the extra thickness. This weakens and irrevocably changes the look of the sash. The storm windows are likely ¾” – 1” maximum in depth.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Verdana",sans-serif;color:black'>You can accomplish the same or better heat retention by renewing the window putty where required on both the double hung sash and storms and by improving or including weather stripping between the vertical rails of the double hung sash and the jamb as well as the between the lock rails of the upper and lower sash and between the bottom rail and the sill. Any double hung sash that are to be permanently fixed shut can be caulked to prevent air leakage. The storms can also be weather stripped or caulked (if permanently fixed) but a small gap between the bottom rail and the sill should be left open to allow moist air to escape in order to prevent the double hung windows from constantly fogging up and causing eventual damage. I can’t tell from the picture, but if the 3 vent holes in the storm sash do not have a flap installed on the inside face to close them off this can be added to cut excess air flow during the cold season.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Verdana",sans-serif;color:black'>Happy to discuss further.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Verdana",sans-serif;color:black'>Regards<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Verdana",sans-serif;color:black'>Davyd <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Verdana",sans-serif;color:black'>(restoration carpenter)<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Verdana",sans-serif;color:black'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-CA style='font-size:12.0pt;font-family:"Verdana",sans-serif;mso-fareast-language:EN-GB'>Davyd McMinn<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA style='font-size:12.0pt;font-family:"Verdana",sans-serif;mso-fareast-language:EN-GB'>President<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA style='font-size:12.0pt;font-family:"Verdana",sans-serif;mso-fareast-language:EN-GB'>Ross Bay Villa Society<o:p></o:p></span></p><p class=MsoNormal><a href="http://www.rossbayvilla.org/"><span lang=EN-CA style='font-size:12.0pt;font-family:"Verdana",sans-serif;color:#0563C1;mso-fareast-language:EN-GB'>www.rossbayvilla.org</span></a><span lang=EN-CA style='font-size:12.0pt;font-family:"Verdana",sans-serif;mso-fareast-language:EN-GB'><o:p></o:p></span></p><p class=MsoNormal><a href="mailto:info@rossbayvilla.org"><span lang=EN-CA style='font-size:12.0pt;font-family:"Verdana",sans-serif;color:#0563C1;mso-fareast-language:EN-GB'>info@rossbayvilla.org</span></a><span lang=EN-CA style='font-size:12.0pt;font-family:"Verdana",sans-serif;mso-fareast-language:EN-GB'><o:p></o:p></span></p><p class=MsoNormal><a href="http://www.facebook.com/rossbayvilla"><span lang=EN-CA style='font-size:12.0pt;font-family:"Verdana",sans-serif;color:#0563C1;mso-fareast-language:EN-GB'>www.facebook.com/rossbayvilla</span></a><span style='font-size:12.0pt;font-family:"Verdana",sans-serif;mso-fareast-language:EN-GB'> </span><span lang=EN-CA style='mso-fareast-language:EN-GB'><o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA style='mso-fareast-language:EN-GB'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Verdana",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Verdana",sans-serif;color:black'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Verdana",sans-serif;color:black'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Verdana",sans-serif;color:black'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:"Verdana",sans-serif;color:black'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US style='mso-fareast-language:EN-GB'>From:</span></b><span lang=EN-US style='mso-fareast-language:EN-GB'> bcma-bounces@lists.vifa.ca <bcma-bounces@lists.vifa.ca> <b>On Behalf Of </b>Moderated BCMA subscriber listserv.<br><b>Sent:</b> 02 April 2019 12:02<br><b>To:</b> bcma@lists.vifa.ca<br><b>Subject:</b> [BCMA] Window Glass Replacement<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span lang=EN-CA>Hi everyone,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-CA>We are currently planning a project to restore the windows of the 1924 heritage building that houses our museum.
