Abstract

Procedure for manufacturing a double-walled element, characterized in that it comprises the steps of selecting two sheets, a first sheet that has a perimeter adjusted entirely within or coupled to the perimeter of the second sheet, at least one of the sheets being of thermoplastic material, and the other (which does not need to be made of thermoplastic material) provided with at least one opening to allow the passage of air, providing means to join the two sheets and heat at least one thermoplastic sheet to a temperature above the softening point of the thermoplastic sheet, tensioning the heated thermoplastic sheet relative to the other sheet, joined by a difference exerted in atmospheric pressure, and allowing the element to cool below the softening point of the thermoplastic material.
