목재 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 목재 with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates.
Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.
깊이 읽기
목재 (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.
목재 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.
This atlas treats 목재 as a system: mill route, coatings, tests and the cavity it sits in.
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.
Origin: Palaeolithic tools; CLT 1990s Austria, Global forests / Graz. The process chapter follows feedstock → conversion → forming → finish → install.
Uses span buildings to defence / safety. Pairings matter: steel.
Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.
Circularity mark 76/100. Ask which scrap, which certificate, which year.
