So we recently started this thread about spray foam and fire concerns:

We have our kit purchased and ready to go, but then got a little freaked out when we realized just how flammable the stuff is.
We've been weighing our options for a week. The two main things we considered were returning our kit and getting roxul comfortboard insulation or using the spray foam along with a fireproof coating.
We're currently leaning towards using the spray foam, covered with plywood, and coating it with intumescent paint.
We have a couple of questions...
1. Would you put the intumescent paint directly on the foam, just on the plywood, or on both the plywood and foam? (keep in mind this stuff is expensive)
2. Do any of you have experience with any of the many brands of intumescent paint out there? Is there any major difference or will they all perform similarly?
