[BCMA] Window Glass Replacement

[Moderated BCMA subscriber listserv.]

When I visited the Royal Monuments Archive in Swindon England during
participation in the Unesco TICCIH conference in 2000, I noted that they
put a second window of the same type in the window opening.  The most
obvious effect was that you saw what appeared to be an original window on
the outside and an original window on the inside but with an air gap
between the two.  In such a case both inside and outside sash could be
opened for ventilation.  The air deflector is clearly shown in the
photograph.  I presume it was to slow down any breezes.

For my taste preserving the original glass is always best.  I do remember
a vintage house work shop where one owner announced that all the original
wavy glass had been replaced.  The heritage contingent was horrified.

The Swindon solution shows that it is possible to preserve the original
windows and their appearance, still do better on retaining heat or cold,
reduce UV, light, or heat in the qualities of the glass in the new sash.

I have added a couple of photographs.
