Abstract: A fire shutter for preventing the spread of fire and smoke through an opening such as a door in a building structure that is resistant to pressure from a high-pressure hose. A flexible coated fabric composite, using high-temperature and high-pressure resistant materials. The shutter combines two layers of texturized fiberglass fabric, wherein each layer combines fiberglass and wire strands, with one strand wrapped in a spiral around the other, in both the warp and weft directions. The fabric is impregnated with vermiculite. Each layer of fabric, containing the fiberglass and wire strands, is coated, on an outer portion, with a high temperature stabilized, functionally filled polymer. After exposure to an extreme temperature condition, immediately followed by a standard hose test, the fire shutter functions as a fire partition, without smoke, fire or water penetration, while remaining flexible and allowing for egress.
