Abstract
A three-dimensional vacuum thermal insulation element having a compressed three-dimensional porous structure and a shell closed in an airtight manner. The shell includes a thermoformable barrier wall and encloses the porous structure arranged between two major surfaces of said barrier wall. The porous structure has a pressure of between less than 105 Pa and more than 10-2 Pa at ambient external temperature and pressure. The barrier wall is thermoformed at the site of said two major surfaces, between which the porous structure has a curved shape and/or reliefs and/or depressions.
