A teardrop and a high-rise are not very comparable on fire risk, especially given that polymetal is approved under US fire regs for buildings under 40 feet tall. (according to the Wikipedia article you referenced). Yes, if you apply two crossed torches to the teardrop skin for 30 minutes (or tip over a combustion heater), your trailer may burn. Just like all the other trailers made of plywood and filled with wood cabinetry and combustible fabrics.

The basalt fiber doesn't seem comparable because it is a fabric and not a rigid panel. I'd love to build a trailer out of fabric and resin, but it requires a lot more skill and time to make it look good and perform well than fitting together some rigid panels.
I found references to some prototype basalt wall panels, but other than simulated stone cladding, no commercial products. Is a basalt alternative panel to polymetal out there?
