Pro tip: That container home tour in Austin last month made me rethink my whole insulation plan

I was at the Green Builders Expo in Austin and saw a guy who used double-layer rigid foam board instead of spray foam, claiming it saved $2,000 on his 40-foot container, but now I'm worried about moisture trapping - has anyone else tried this method and seen issues with condensation between the layers?

Double-layer rigid foam board" for a container? That's wild.

Honestly, double-layer foam board is a game changer for container builds. Tried it on a shipping container bunkhouse last year and the temp difference was insane compared to single layer. Ngl, it's messy to install but totally worth the hassle for insulation that actually works.
