My original plan was to have some air space between the two layers of foam (giving a tiny bit more insulation) and then a piece of paneling or drywall to finish out the opening. A picture frame molding around the outer panel and voile’. But while at the home center, the obvious alternative was sitting right there in the building materials bins: pegboard! I have always used pegboard in the darkroom for hanging reels, negative carriers and other such tools. I decided to substitute pegboard for the outer panel. This also led me to place the two foam panels together to allow enough space behind the pegboard for the hooks to clear.
The result was more than satisfactory, and can be turned back into a working window with minimal effort and some touch up paint.
