Re: Insulate Stained Glass Window for Winter
Most often people mount plexiglass on the outside. You can use aluminum bar stock to add dividers as needed to accommodate the available plexi size you can find. Try to align the crossbars as best you can so as not to interfere with the design. If the window faces south, you should be aware that the greenhouse effect is going to speed up the deterioration of the window. But you are already aware that it needs repairs. A re-leading (basically taking the thing apart and replacing the ruined/worn-out lead) is going to require removal. Can't be done standing in place, must be laid flat; so having such a storm window will give a good temporary enclosure while that's being done.
Remove not the ancient landmark, which your fathers have set.
