Abstract
The heat-insulating panel designed to be applied against a wall to be protected consists of two parallel sheet-metal sealing elements of small thickness which are welded together at their periphery and form an enclosed space in which is mounted a stack of thin wire-fabric elements and perforated plates or grids in alternate relation. The free spaces between the wire-fabric elements and the perforated plates communicate with each other and are filled with an inert gas. A leak-tight welded joint is formed between the non-perforated peripheral portion of the plates and the sheet-metal sealing elements.
