I'm wondering if 'total collapse of cell walls and the complete densification of the natural wood with highly aligned cellulose nanofibres.' means that stuff isn't going to burn until you get temperatures where steel melts anyway?
> Massive wood walls and structural beams and columns comprised of engineered panels have demonstrated fire performance equal to concrete and, in some cases, superior to steel
one big difference seems to be that once the critical point is reached, even if the threshold very high, the wood contributes to the fire and nourishes it, unlike concrete or steal. a skyscraper with proper sprinkling should be fine.
