Intermediate layer meant for passive heat protection of preserved object, realizes functions of heat isolator due to low heat conductivity of fire-resistant dry porous material forming this layer. Internal layer realizes active heat protection of microelectronic register. To reach aforementioned goal it is formed of crystalline compositions, containing crystallization water - crystalline hydrates, under effect from external heat consuming external heat and thus during whole time of heat-caused dehydration upholding temperature inside protected volume to be below temperature of heat decomposition of crystalline hydrate. To increase efficiency of heat protection, internal layer on both sides is covered by metallic heat-reflective inserts.
