I used 1 and 2 inch thick polyisocyanurate foam sheet. I used the exposure rated type but you can also get it with regular foil backing on both sides at Home Depot (not Lowes).

I cut it with a jigsaw using a wood cutting blade...much easier than a knife and generates little dust unlike a table saw. I did wear a dust mask. I did our entire camper so know a bit about the stuff now.
