Abstract
Disclosed is an FR barrier that may be used to enhance the fire resistance characteristics of a product, and an associated method for forming such an FR barrier. The FR barrier includes a chemical barrier layer and an FR nonwoven fiber batt. The chemical barrier layer improves the FR characteristics of the FR nonwoven fiber batt, often by depriving flame of oxygen, while the FR nonwoven fiber batt may shield a combustible layer of a product from direct contact with flame. The chemical barrier layer is often applied to the distal side surface of the FR nonwoven fiber batt.
