Strength band
blankets tear; modules are folded and anchored
Numbers below are bands used by working engineers, not live quotes. Tensile note: blankets tear; modules are folded and anchored.
Fire performance in this atlas is editorial. Real projects need the assembly report.
Mécanique
Stiffness
Modulus follows chemistry and orientation — not the marketing nickname.
Toughness
Crack growth, not peak stress, retires most real parts.
Fatigue / creep
Cyclic and time-dependent damage dominate certificates issued on static coupons.
Hardness / hand
Indentation, drape or compressive class — whichever the trade actually measures.
Thermique
Conductivity
λ rises with T; still far below brick — Fibre céramique is used as insulation.
Service temperature
Melting / softening / decomposition band: classification T often 1260–1400 °C.
Expansion
Joints and clearances must follow the expansion class of Fibre céramique, not of steel-by-habit.
Thermal mass
Density 64–192 kg/m³ blankets sets how fast a section changes temperature.
Ageing of λ
Foams, VIPs and moist batts drift; quote aged values.
Électrique
Conductor or dielectric
Fibre céramique is generally a dielectric or semiconductor film, not building wire.
Static / EMI
Fillers and moisture change resistivity more than brochures admit.
Standards language
IACS, volume resistivity or dielectric strength — pick the quantity the job uses.
Feu
Reaction to fire
Typical declared class: A1. This is not a universal passport.
Resistance vs reaction
Euroclass is reaction. EI/R ratings are assemblies — boards, coats, cavities.
Melt-drip / char
Fibre céramique tends to char or stay inorganic rather than melt-drip like commodity olefins.
Smoke / toxicity
CO, HCN, HF or fibres — the species depend on chemistry. Name the test (ISO 5659, EN 45545, NFPA 1971).
If a salesperson quotes a single “safety score”, ask which standard, which thickness, which year.
