So as some of you know, Ron used aluminum flashing, spray foam, and fiberglass to create the outside of his shell. I’m modifying the procedure a bit to hopefully be able to take mine apart in smaller pieces.

Instead of using flashing, I’m using 1/8-inch hardboard to cover the inside. It bends easily with the grain, but against the grain, not so much. I don’t need much bending against the grain, but I don’t want the covering to distort the frame. To solve that problem I fluted the panels using a table saw to assist with their flexibility. This seems to be working well, so I may use this technique on the outside of my shell too. To get the hardboard to bend more easily in both directions (compound) I was thinking I could create fluting in both directions. The good thing about this approach is that one side of the board is still smooth. There are limitations to how much you can bend it, but I think it will work.
