Abstract

The present invention relates to a combination of at least one envelope (20) for a laminar structure (100) providing adaptive thermal insulation, and a heat pro-tection shield (50) for the envelope (20), the envelope (20) enclosing at least one cavity (16) having included therein a gas generating agent (18) having an unactivated configuration and an activated configuration, the gas generating agent (18) being adapted to change from the unactivated configuration to the activated configuration, such as to increase a gas pressure inside the cavity (16), in response to an increase in temperature in the cavity (16), the envelope (20) being configured such that a volume of the envelope (20) increases in re-sponse to the increase in gas pressure inside the cavity (16), the heat protection shield (50) being assigned to the at least one envelope (20) such as to cover at least a heat exposed side of the envelope (20) with respect to a source of heat (700).
