Hi! I am relatively new to the vanlife community and I have some questions about insulation.
I recently bought a 2000 Ford Econoline and I’m ready to start insulating it. My question is: what is the most efficient way to insulate these inconvenient wall panels that the Econoline has provided me?? My plan was to use polyiso board for the wall/ceiling but I have run into a mental block while trying to figure out how to insulate the walls. As you can see (in the picture below) they are not flat walls like I have seen in most van builds. I was wanting to stay away stuffing fiberglass insulation in the empty pockets between the outer wall and the “inner wall” - I know they make things like sheep wool to replace fiberglass, but how well does that insulate and would I have to build a moisture barrier?
I have done a bit of homework on different brands/types of insulation but I don’t want to screw anything up too badly or cause moisture buildup if I can help it. Any insight would be MUCH appreciated.
