Quick answers
Is Cotton non-combustible?
Declared reaction class in this atlas: combustible fibre (treatments vary). Assemblies still need resistance tests.
Does Cotton insulate?
Thermal mark 40/100 versus the atlas. Conductivity note: low (textile still air).
What is the density band?
~1.54 g/cm³ fibre
How is it made?
Origin story: Indus / New World domestication; mill 18th c. (India / Americas / Lancashire).
Can it be recycled?
Circularity mark 54/100 — editorial, route-specific.
Typical melting or failure heat?
