Quick answers
Is Bamboo non-combustible?
Declared reaction class in this atlas: untreated D-class typical; treated products vary. Assemblies still need resistance tests.
Does Bamboo insulate?
Thermal mark 40/100 versus the atlas. Conductivity note: ~0.1–0.2 W/m·K across the wall.
What is the density band?
~0.6–0.8 g/cm³ culm
How is it made?
Origin story: ancient scaffolding; industrial strand board late 20th c. (East and South Asia).
Can it be recycled?
Circularity mark 86/100 — editorial, route-specific.
Typical melting or failure heat?
chars; does not melt

Numbers below are bands used by working engineers, not live quotes. Tensile note: high along the fibre; nodes and glue lines dominate engineered boards.
Fire performance in this atlas is editorial. Real projects need the assembly report.
Mechanical
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.
Thermal
Conductivity
~0.1–0.2 W/m·K across the wall — Bamboo is not a substitute for a dedicated λ layer.
Service temperature
Melting / softening / decomposition band: chars; does not melt.
Expansion
Joints and clearances must follow the expansion class of Bamboo, not of steel-by-habit.
Thermal mass
Density ~0.6–0.8 g/cm³ culm sets how fast a section changes temperature.
Ageing of λ
Foams, VIPs and moist batts drift; quote aged values.
Electrical
Conductor or dielectric
Bamboo 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.
Fire
Reaction to fire
Typical declared class: untreated D-class typical; treated products vary. This is not a universal passport.
Resistance vs reaction
Euroclass is reaction. EI/R ratings are assemblies — boards, coats, cavities.
Melt-drip / char
Bamboo can burn or drip; do not treat it as A1 without a system test.
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.
