Was at UL when the Xanadu projects were being constructed. There are fire retardants that can be used with polyurethane to reduce the flame spread & penetration (at least enough to get a UL listing),...however, as with most dome homes, ventilation is the main factor to consider in a climate such as Puna.
The last Xanadu (in Kissamee, FL) was demolished, in large part to the amount of mold & mildew that developed when it was no longer cared for as a tourist spot...
The big thing with all of these dome structures is the ventilation in the dome...unless the ventilation is well engineered, water vapor will develope into a huge problem...
