A three-dimensional, vacuum thermal insulating element comprising a compressed three-dimensional porous structure, an envelope closed in an airtight manner comprising a thermoformable barrier wall, enclosing the porous structure, which is interposed between two major surfaces of the barrier wall, and where, at outside ambient temperature and pressure, a pressure between less than 105 Pa and more than 10−2 Pa prevails. The barrier wall is thermoformed at said the two major surfaces, between which the porous structure is bent-shaped and/or has reliefs and/or depressions.
