Does high humidity damage Wool Carpet?
No. Wool carpet will absorb water vapor from the air in humid conditions and then release it when the atmosphere becomes dry. Because of this absorbency, wool carpets also tend to resist static electricity and naturally be flame resistant, so no added flame retardant is needed. The Wool fiber will not support combustion and is difficult to ignite, it does not melt or drip and self-extinguishes. Carpet that does char can easily be brushed away. This is why buildings that have stringent flammability regulations choose wool. Think casinos and hotels.
