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

Prices are bands. A 2024 coil is not a 2026 contract. Labour and certification often dwarf the commodity.
Producers listed are landmarks for orientation, not a ranking or a procurement list.
