I have an old basement door that has this weird window that consists of a bunch of glass panels that can be opened and closed like blinds with a handle.
I lose a lot of heat in the winter through this window, so I want to get rid of it. One option is to replace the whole door.
I am curious, though, if it's possible to replace just the window with some sort of standard or custom-made double-pane insert. Who makes/sells such windows?
