Structure, lining, insulation or finish depending on family.
Ceramic fibre · Spun refractory fibres for 1000–1400 °C — kiln linings, gaskets, and a respirable-fibre caution that AES grades try to ease.
Darker cells mean a higher score for this topic on that metric.

Declared reaction class in this atlas: A1. Assemblies still need resistance tests.
Thermal mark 80/100 versus the atlas. Conductivity note: λ rises with T; still far below brick.

Ceramic fibre earns its keep in systems: a beam, a batt, a fibre blend, a coated steel — rarely a lone coupon.
