The current hexayurt design with foam is cool, for numerous reasons, fire safety is not one of them. I can't imagine it being too much worse than being in a flaming tent, except for maybe a false sense of security with internal fires. It is hard to ignite the foam with a flame and it doesn't spread much, but I only performed open-air fire tests. If what Chris says is true, we should consider other materials if possible or do as we have done in the past and maintaned a strick to smoking/open flame rule in the hexayurt.
