Abstract: A temperature-sensitive, heat-producing article, such as an electric cable, is fire protected by a multi-layered, thin, light weight, and vented arrangement with enhanced low-temperature heat dissipation during normal operation and effective high-temperature heat blocking during a fire. It includes a. an inner layer of heat blocking material chosen from the class of reactive endothermic materials (14), b. a vented, thin, multilayered heat screen (10), c. a gap producing spacer (12), and d. in combination, enhanced conductive, convective, and radiating elements for heat dissipation at low temperatures (11, 12, 41, and 44). The screen (10) includes a plurality of alternating layers of porous, ultra-thin, high-temperature, non-wicking insulating fiber cloths, and high-temperature heat-reflecting metallic porous foils with a layer of metallic wire cloth on the outside, i.e, the side facing the fire.
