Quick answers
Is Ceramic fibre non-combustible?
Declared reaction class in this atlas: A1. Assemblies still need resistance tests.
Does Ceramic fibre insulate?
Thermal mark 80/100 versus the atlas. Conductivity note: λ rises with T; still far below brick.
What is the density band?
64–192 kg/m³ blankets
How is it made?
Origin story: 1940s–60s US/JP; EU RCF classification 1990s (United States / Japan / EU).
Can it be recycled?
Circularity mark 34/100 — editorial, route-specific.
Typical melting or failure heat?
classification T often 1260–1400 °C

Ceramic fibre earns its keep in systems: a beam, a batt, a fibre blend, a coated steel — rarely a lone coupon.
Products below are cultural landmarks as much as SKUs.
Sectors
Transport
Mass, fire and fatigue rewrite the grade list.
Energy
Heat, voltage and hydrogen compatibility.
Consumer
The volume that pays for the mill.
Medical / food
When allowed — extractables and allergies matter.
Defence / safety
Ballistics, FR clothing, fire stops.
