Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number. Wood is sold as grades, not as a single substance. Chemistry cellulose–hemicellulose–lignin, density 0.3–0.8 g/cm³ typical, heat band chars ~200–300 °C; does not melt.

Wood · Wood is one of 32 materials in this atlas, grouped under ceramic
Wood is one of 32 materials in this atlas, grouped under ceramics: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue. Scores compare Wood with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates.

Conductivity note: ~0.1–0.2 W/m·K along vs across grain. Insulation score 56/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: D–B depending on product / treatment. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
Wood · paras 1
Origin: Palaeolithic tools; CLT 1990s Austria, Global forests / Graz. The process chapter follows feedstock → conversion → forming → finish → install. Wood (cellulose–hemicellulose–lignin) is a family of grades whose density 0.3–0.8 g/cm³ typical, heat band chars ~200–300 °C; does not melt, and fire letter D–B depending on product / treatment.
