ABSTRACT:
A generally elongated, thin, metal sheet heat insulator (1) having at least two generally elongated, thin, metal sheets (3, 4, 5, 6 and 7) disposed generally one above the other in a spaced apart relationship and a metal separator (2) therebetween contacting both sheets for maintaining the spaced apart relationship. The improvement of the invention has distinct, non-woven, substantially open, metal separators (2) having a substantial Z-direction dimension (27) and have substantially parallel upper and lower contact surfaces (27, 29) spaced apart in the Z-direction (27) with a contact surface area of each contact surface less than about 30% of a planar area (48) of the separator parallel to the X and Y-dimensions of the separator.
