An isolation unit comprising: a core (2) produced from a porous insulating material; an outer casing (3) produced from a deformable impervious material forming a sealed inner space (9) in which the core of the isolation unit is positioned, said inner space having, in an operational state of the isolation unit, a vacuum relative to an environment (16) outside the isolation unit; - an element (24, 24A, 24B, 42, 43) for degrading the casing, suitable for degrading the casing in response to an overpressure in the inner space of the casing relative to the environment outside the isolation unit causing a deformation of the casing, the degrading of the casing by the degrading element bringing the inner space of the casing into communication with the environment outside the isolation unit. |
