I have a similar pop up. I was just going to make solid walls out of 3/4" foam, wood framed, covered with canvas. The corners would either be velcro attached strips of canvas or maybe hard corners made of canvas covered foam. Looking at combination storm windows because they are thin. Still have to figure out a way to hinge the panels so they fold down when I lift the top.
