The lamina structure 10 provided by this invention provides adaptive insulation and is provided between the first layer 26, the second layer 28, the first layer 26 and the second layer 28. At least one outer cavity 22, at least one inner cavity 16 surrounded by the envelope 20, an envelope 20 contained within the outer cavity 22, and an inactivation configuration and an activation configuration The gas generator 18 is deactivated to include a gas generator 18 and to increase the gas pressure at least inside the internal cavity 16 in response to an increase in temperature in the internal cavity 16. Suitable for changing from a configuration to an active configuration, the first layer 26, the second layer 28, the outer cavity 22 and the inner cavity 16 increase the gas pressure inside the inner cavity 16. In response, the distance D between the first layer 26 and the second layer 28 is arranged to increase. |
