Sorry for my rash statement, but your supposed to have plywood over the foam insulation.
How thick do you think it is? Maybe 3/16 of an inch?
Plywood thickness depends on what joist spacing you have. Buying plywood versus OSB is such a negligible cost increase when considering the much lower quality and problems associated with OSB.
Tell that to Thor and Forest River, as laminated floors used in RVs may have what they consider joists as far apart as 4-5 feet, the same as in laminated walls. I've drilled through 5 or 6 over the years and all had 3/16" luan on top and 1/8" luan on the bottom of the lamination.
