Wood in 1906: Glulam patents

Read the condition on Wood before the nickname. Year 1906, line “Glulam patents,” figure 0. The usual 30–60 min lining on timber. A material is what it is made of, the condition it survives, and where it goes afterward. Wood under “Glulam patents” in 1906 should say which, with 0 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.

Scores compare Wood 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.

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. 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.

This atlas treats Wood 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.

The label keeps Wood, 1906, and 0. “Glulam patents” is the condition on the figure.1906
