Cross-laminated wood is apparently very stable. People also ask about fire resistance, but the outermost layer gets charred which then protects the inner for quite some time, compared to traditional steel beams where the heat makes the steel soft. So even though the steel doesn't burn, it needs special fire protection to stay stable for long enough for people to evacuate.
