NEURODESIGN® · MATERIAL CLASS · ANIMAL AND PLANT FIBRE
Wool
Keratin fibre, typically used as pile or felt. Hygroscopic, inherently flame resistant without added retardants, and porous enough to absorb sound at speech frequencies when used in depth.
Decisive attributes
The attributes that most determine how this class behaves and how it is experienced. No values are shown, because a value belongs to a product and not to a class. Two products of the same material can differ from each other by more than the material differs from its neighbours.
Typical application
Broadloom. Rugs. Upholstery. Acoustic felt. Wall panels.
Worth watching
Wool is commonly specified as the low-emitting choice, but the emissions profile of a wool carpet is usually governed by its backing, adhesive and stain treatment rather than by the fibre.
Evidence
No record in the research corpus tests human response to this material class. Its physical behaviour may be well understood and its properties may be entirely predictable from the attributes above. That is a different thing from evidence that a person responds to it, and this library does not convert one into the other. The absence is shown rather than filled.
Outcomes it could bear on
Outcomes whose material levers overlap this class. This is a structural relationship in the ontology, not a finding: it says the property is relevant to the outcome, not that this material produces it.
