A non-combustible blanket material (52) is provided for use in manufacture and construction application to prevent the spread of flames and heat. The blanket material (52) includes a substrate layer made of inorganic fibers (12) formed into a fireproof, porous cloth (20). In addition, a heat-expandable non-combustible layer (18) is permanently affixed to one side of the substrate layer. This flame retardant layer (18) includes a combination of fireproof manufactured fibrous material of relatively short length and random orientation, heat expandable particles of temperature sensitive material, and a fireproof adhesive for binding the fibrous material and the heat expandable particles together as well as binding the combination to the substrate layer. The heat expandable particles (18) are adapted to increase the thickness of the flame retardant layer when subjected to temperatures substantially in excess of ambient. |
