석고보드 is one of 32 materials in this atlas, grouped under fire: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue.
Scores compare 석고보드 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
석고보드 (CaSO4·2H2O + paper faces) is a family of grades whose density ~700–1000 kg/m³, heat band calcines ~80–180 °C (dehydration), and fire letter A2-s1,d0 typical; core A1.
석고보드 is sold as grades, not as a single substance. Chemistry CaSO4·2H2O + paper faces, density ~700–1000 kg/m³, heat band calcines ~80–180 °C (dehydration).
This atlas treats 석고보드 as a system: mill route, coatings, tests and the cavity it sits in.
Conductivity note: ~0.17 W/m·K. Insulation score 34/100 is relative to 32 entries — metals lose, VIPs and aerogels win.
Fire letter in editorial use: A2-s1,d0 typical; core A1. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
Origin: Sackett 1894; US Gypsum 1916, United States. The process chapter follows feedstock → conversion → forming → finish → install.
Uses span buildings to defence / safety. Pairings matter: mineral-wool.
Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.
Circularity mark 62/100. Ask which scrap, which certificate, which year.
