Bamboo in 1940s: Wartime substitutes

Scores compare Bamboo 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.

Bamboo (cellulose–hemicellulose–lignin) is a family of grades whose density ~0.6–0.8 g/cm³ culm, heat band chars; does not melt, and fire letter untreated D-class typical; treated products vary. Bamboo is sold as grades, not as a single substance. Chemistry cellulose–hemicellulose–lignin, density ~0.6–0.8 g/cm³ culm, heat band chars; does not melt.

This atlas treats Bamboo as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: ~0.1–0.2 W/m·K across the wall. Insulation score 40/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: untreated D-class typical; treated products vary. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
