Bamboo in 1940s: Wartime substitutes · 410
Scores compare Bamboo with the rest of the atlas on strength, heat, fire behaviour, insulation, workability an Read the condition on Bamboo before the nickname. Year 1940s, line “Wartime substitutes,” figure 1940. Furnaces and reactors already run on PID. A material is what it is made of, the condition it survives, and where it goes afterward. Bamboo under “Wartime substitutes” in 1940s should say which, with 1940 tied to the condition. A figure with no condition is a boast. Readers meet the name on the back of a product, so the code and the history should not share one sentence.

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.
