I have a fair amount of used foam board. The kind used for meeting display boards. It looks like closed cell foam. It's also backed on both sides with paper. You can find it at any crafts store.
My question is how successful would it be to use for insulation. As its 1/4" thick I thought about maybe doubling it up to get a 1/2" thickness.
Could even glue tin foil to the exterior side as a radiant barrier.
What do you think?
