Process energy / dust
Mills, fibres, isocyanates, metal fume or silica — name the actual agent.
Bamboo · A fast grass culm sold as timber — scaffolding, flooring and a glue story that decides the indoor air.

Declared reaction class in this atlas: untreated D-class typical; treated products vary. Assemblies still need resistance tests.
Thermal mark 40/100 versus the atlas. Conductivity note: ~0.1–0.2 W/m·K across the wall.
~0.6–0.8 g/cm³ culm
Origin story: ancient scaffolding; industrial strand board late 20th c. (East and South Asia).
Circularity mark 86/100 — editorial, route-specific.

Safety here is encyclopedia, not a workplace assessment. Name the agent: dust, isocyanate, fibre, fume, moisture, fire.
Fire class untreated D-class typical; treated products vary is reaction language unless an assembly test is cited.
Mills, fibres, isocyanates, metal fume or silica — name the actual agent.
Corrosion, moisture, UV or creep silently retire sections.
Smoke, drip, fibres or toxicants depend on chemistry.
Handling injuries are more common than brochure failures.
The wrong grade is the most expensive hazard.

Assemblies (EI, R, Type X) are not implied by the material letter.
EN 13501, ASTM E84, ISO 5660, KS F 2271 — they do not equal each other.
Clothing FR and steel R-ratings are different professions.
Better-than-average loop for this atlas, still not zero.
Additives, dusts and processing aids (not always the polymer backbone) drive regulation.
Process water, leachate or moisture swelling.
Sortability beats theoretical recyclability.
Grade mix-ups scrap lots.
Fibres, isocyanates, UV, sharp edges — not a generic “chemicals” pictogram.
Coatings and cavities change the letter.
Installation is in the specification.
Codes move. Recheck KS, JIS, EN, NFPA and IBC editions for the job’s jurisdiction.
Frozen silicate liquid — windows, bottles, fibres and a Euroclass A1 skin that still shatters and melts in fire.
Overall 58 💎Crystalline oxides and carbides for heat, wear and electronics — not the mug on the desk.
Overall 64 🏗️The hydraulic ceramic of cities — cement, water, rock and usually steel, with a fire story better than exposed steel.
Overall 57 🌲Anisotropic cellulose composite grown as trees — carpentry, mass timber and a combustible story that codes still manage.
