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

Making Ceramic fibre is a chain: feedstock, conversion (1940s–60s US/JP; EU RCF classification 1990s), forming, heat, finish, install.

Process steps
02 Conversion
1940s–60s US/JP; EU RCF classification 1990s
03 Forming
Cast, spin, weave, sinter, foam, laminate or coat — the step that sets anisotropy.
04 Heat / cure
Temper, vulcanise, calcine or dry: skip it and the datasheet is fiction.
05 Finish
Coatings, sizings, facers, galvanizing, anodising, painting.
06 Install
Fasteners, adhesives, DFT, compression, dryness — site quality is a material property.
Routes
Primary
Virgin route around United States / Japan / EU.
Recycled / secondary
Recycling exists but quality or energy often disappoints.
Specialty
High-spec grades leave the commodity mill.
Site-applied
Coatings, sprays, casts — the factory is sometimes a jobsite.

Hard limits
Envelope
Melting/softening classification T often 1260–1400 °C; conductivity λ rises with T; still far below brick.
Environment
Moisture, UV, chlorides, alkalis or oxygen — pick the one that actually kills Ceramic fibre.
Code
Fire class A1 is a starting letter, not a wall rating.
Process energy and scrap quality belong in the carbon passport, not in a footnote.
