WebWool’s inherent fire resistance comes from its naturally high nitrogen and water content, requiring higher levels of oxygen in the surrounding environment in order to burn. Wool … WebWool’s inherent fire resistance comes from its naturally high nitrogen and water content, requiring higher levels of oxygen in the surrounding environment in order to burn. Wool may be ignited if subjected to a significantly powerful heat source, but does not normally support flame, and will instead smoulder, usually only for a short time.
