PolyMetal [I]vs[/I] Basalt fiber

Times past I have advocated for PolyMetal as a construction material.

Experiments resulted in my wanting to make a teardrop trailer from it:



However, it comes to my attention that this is the same material used in cladding Grenfell Tower, which burned to the ground! Combustibility may not be a deal-breaker for an airdam, etc., but it is for sleeping inside it. Not a problem for basalt fiber: https://en.wikipedia.org/wiki/Basalt_fiber#Properties

Thermal performance: Super-thin basalt fiber

Nano-glass-coating before adding the resin matrix makes it as cool looking as carbon fiber:

So — in summary — forget everything I said about PolyMetal. Thank you.
