Disclosed is a heat absorptive bi-layer FR nonwoven fiber batt and an associated method of enhancing the fire resistance characteristic of a product employing the same. The heat absorptive bi-layer FR nonwoven fiber batt includes a heat reactive layer and a barrier layer having a lower side surface disposed against an upper side surface of the heat reactive layer. In response to a heat source located beyond the barrier layer, a cavity may form in the heat reactive layer, extending from the upper side surface to an interior side surface thereof. The cavity is fully enclosed, within the heat absorptive bi-layer FR nonwoven fiber batt, by the lower side surface of the barrier layer.
