ABSTRACT:
A passive system for protecting a structure against high temperatures which consists of a thin protective foil of heat-resistant material such as stainless steel fastened to the face of the structure to be protected. When subjected to high heating rates, the local thermal expansion of the foil forms a blister bulging away from the structure to thereby create an air space which thermally insulates the structure.
