Abstract

The invention relates to a laminar structure (10) providing adaptive thermal insulation, comprising a first layer (26), a second layer (28), at least one outer cavity (22) provided in between the first layer (26) and the second layer (28), at least one inner cavity (16) enclosed by an inner envelope (20), the inner envelope (20) being included in the outer cavity (22), and 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 at least inside the inner cavity (16), in response to an increase in temperature in the inner cavity (16), the first layer (26), the second layer (28), the outer cavity (22) and the inner cavity (16) being arranged such that a distance (D) between the first layer (26) and the second layer (28) increases in response to the increase in gas pressure inside the inner cavity (16).
