Single Pane Drop Sash Windows
We seem to have a unique creature. She is a 1968 Chevy C40 with a Carpenter body. And she has single pane drop sash windows, meaning the entire window is one solid piece that slides down into the body wall of the bus.
We were hoping to keep the original windows, at least initially, but they're going to make insulating the walls a bit tricky.
Has anyone else encountered these? What did you do? Any thoughts or suggestions, aside from replacing them?
