[MassHistPres] Fwd: Advice on windows??

[heartwood restoration]

good to hear that you are choosing to keep the original windows...

in our work, we encourage exterior storm sash as the best option as the  work double duty in protecting the primary sash from outdoor elements in addition to adding energy efficiency...for these small fixed sash, the exterior option is simple with a half-lapped wood storm painted black which would not obscure the  glass...

depending on the interior trim/frame configuration, a wood storm can be used here as well...the frame of the storm can match the paint color and the width of the rails and stiles of the primary sash and be installed with a pressure fit..

both interior and exterior options can be installed so there are small gaps at each side for circulation and ventilation...

hope that helps....

  Hi, I received this request from a member of our HDC.  Can any of you provide any advice?  I can send a couple photos if that will help.

  Thanks,

  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??
