[MassHistPres] Fwd: Advice on windows??

I take it this is not an NR listed property.  Otherwise you could ignore the requirement altogether.

But it seems like an exterior glass panel will completely obscure the old sash due to reflections off the glass, just like storm windows usually render old divided light sashes invisible, and transform the window into being two-dimensional, with no texture or relief.   (I've seen plenty of old stained glass church windows made dreadful by the installation of an exterior glass panel.)  One wouldn't see the shadows from the muntins or the  hint  of color from the small pieces of colored glass.  This is  especially the case in our situation because the wood is painted very dark, it is on the north side of the building and is usually in shadow.  I was hoping to figure out a way of having the insulating plane in the interior, i.e. An interior storm panel, thus not changing the exterior appearance.    I'm  not too worried about protecting the sash from the elements because, well, it has lasted this long without protection.  However, introducing an insulating panel in the inside changes the environmental dynamics acting upon the old sash.  I would think some ventilation would be appropriate, at the same time excluding insects and facilitating cleaning, so it was seeming to be a slightly complicated assembly.  Thoughts??

>> At an historic barn renovation project that we’re doing, we have a couple of square windows with different colors of glass that we’d like to retain (actually relocate slightly), but as the Owner and current codes require that they be made more insulating that they are now, I’m trying to figure out the best way to do that.  I was wondering if you have any recommendations or could point me in the direction of information.
>> Each unit is essentially a simple sash about 20 inches square, installed in a diamond orientation (rotated 45 degrees) in a simple wooden frame.  The frames are not really worth saving, and the sashes need some restorative work and some of the glass replaced.  Ideally, the exterior appearance would end up being the same as it is now (no additional lights of glass in front of the unit), so I was thinking of installing it more or less as it was originally, with an added light of insulating glass on the inside for insulation.  But I think I’d need some sort of ventilation between the historic sash and the new insulating glass.  Anyway, I was thinking that rather than trying to invent something, maybe you or someone has solved this problem before.  Any suggestions??
