And…. Here’s how cold it is in Chicago…!!
I just sent a long email to the client, describing how interior high humidity with a single layer of glass - whether stained or regular glass - will always see condensation on the glass, which then freezes when it is -10° outside (or even only “below freezing”)! It will all melt, and should absolutely be sopped up immediately at the window sill, lest the wood be at risk of moisture damage.
Of course, the photos showing the ice were taken at night. No, the ice is not so thick that it blocks the daylight!
Yes, we are in a discussion with the client to have interior, removable storm windows made for these windows. They will allow venting, and should absolutely be taken off when not needed - both of which will extend the life of covered stained glass windows. The interior solution will maintain the exterior lovely sculptural effect of the stained leaded glass windows.
