For years I worked outside on the graveyard shift San Francisco waterfront. I was a reefer mechanic working on shipping containers. Winter nights do get cold there, (home water pipes freeze). We used metal sheds that were open on the front. We moved them from container to container with a forklift. I insulated my shed with sheets of cardboard. I glued several layers together.
It does rain there and is damp with fog. I sealed up the cardboard with latex paint. The paint makes it very water resistant. Probably also acts as a fire retardant. I used an oxygen acetylene torch on a regular basis. Some will say it can burn. Just about everything inside a vehicle will burn. If you don't set it on fire, it won't.
There are advantages and disadvantages to everything. I am leaning towards if it does get wet, can the water dry out easy. In most vehicles from the factory they use floor insulation near the engine area. They use a type of fiber mat, (kind of like the denim insulation). How many people have had their floor rust out, (where they don't use salt on the roads)? Not any here in Southern Nevada. The problem I see with foam is if water does get behind it, (from condensation or whatever), it doesn't dry quickly. Cloth seats, headliners, and carpeting don't seem to mold. I guess it is because they can dry out easy. put them under plastic and let them get wet. Maybe a different story.
