A double-wall vessel has its inner walls spaced from the outer wall by a plurality of insulating spacers, each of which includes a thread stud affixed to one of the walls and reaching toward the other, the length of the stud being greater than the spacing tolerance of the vessel. On each thread stud is screwed a support body of thermally insulating material and arranged such that, wherein the body is screwed fully onto its stud, its maximum distance from the wall on which the stud is mounted is not greater than the minimum spacing between the two walls. |
