The fire risk of foam is not so much from flame sources outside the hexayurt, as from flame in an enclosed foam-faced space. Apparently the foam is such a good insulator that the space will "flash over" in just a few seconds.
Open-air tests of foam flammability do not show what will happen in an enclosed foam-faced space. They used to think foam was fireproof. Then they lost a few buildings. Foil-faced foam shouldn't have quite the same problem, though I'd still worry about the reflected heat accelerating the combustion of any flammable stuff inside.

It looks great guys. I can't wait to see it on the ranch.
