Abstract: A fire protection structure to be affixed to a substrate adapted to be exposed to a heat source, has: an expandable layer containing an intumescent material expandable when exposed to the heat source, the expandable layer expandable, when exposed to a temperature above a temperature threshold generated by the heat source, from a first thickness to a second thickness greater than the first thickness; and a compliant textile structure retaining the expandable layer, at least a portion of the expandable layer disposed relative to the compliant textile structure such that the portion of the expandable layer is disposed between the substrate and the compliant textile structure when the fire protection structure is attached to the substrate, the compliant textile structure deformable with expansion of the expandable layer from the first thickness to the second thickness.
