Structure, lining, insulation or finish depending on family.
Wood · Anisotropic cellulose composite grown as trees — carpentry, mass timber and a combustible story that codes still manage.

Declared reaction class in this atlas: D–B depending on product / treatment. Assemblies still need resistance tests.
Thermal mark 56/100 versus the atlas. Conductivity note: ~0.1–0.2 W/m·K along vs across grain.

Origin story: Palaeolithic tools; CLT 1990s Austria (Global forests / Graz).
Circularity mark 76/100 — editorial, route-specific.

Wood earns its keep in systems: a beam, a batt, a fibre blend, a coated steel — rarely a lone coupon.
