Abstract: An improved insulating panel for tank-like vessels, such as chemical reactors, precipitators and the like is disclosed. The outer surface of the panel is designed so that heat paths from the insulated structure are minimized. This is accomplished by means of a dual fastening system in which surface panels are connected to one another by means of stitching fasteners while the entire panel structure is fastened to its supporting girt by means of mounting fasteners which are positioned beneath the surface panels and which are thus not directly exposed to the outside air. These mounting fasteners are the elements which provide a heat path from the insulated structure to the surface panels and the outside air. Employment of this improved insulation system reduces heat losses through the panels while maintaining cooler surface temperatures on the panels. Both of these features result in reduced heat loss due to convection and radiation.
