That got me thinking - does anyone think a storm window might be a

You cam buy what is essentially a frame and removeable glass. They work
well for windows that do not open. I've not priced them for years, but they
used to be rather reasonable for what you got. The fram mounts inplace with
screws, the window fits in with clips that make it easy to take out for
cleaning.
