I found a local source of closed cell foam, in rolled sheet of 60" wide and 3/4" thick, I forget how long, but the log is 36" in diameter. It's about $500 a roll with shipping, that seems expensive to me. If you want a 4' x 8' sheet it's over $100 closer to $200, and there are more than five sheets in a continuous roll.
