Improved compact insulation panel is provided which is comprised of two adjacent metal sheets spaced close together with a plurality of spherical, or other discretely shaped, glass or ceramic beads optimally positioned between the sheets to provide support and maintain the spacing between the metal sheets when the gases therebetween are evacuated to form a vacuum. These spherical glass beads provide the maximum support while minimizing thermal conductance. In its preferred embodiment; these two metal sheets are textured with ribs or concave protrusions i...
A thermal insulating panel comprising two hard metal sidewalls positioned in closely spaced apart relation to each other and welded together around their edges to enclose a vacuum chamber therebetween, said chamber being evacuated, and a spacer positioned in said chamber between said two sidewalls for bracing said two sidewalls apart, said spacer comprising a thin substrate sheet having a plurality of protrusions extending transversely outward in opposite directions from opposite surfaces of said substrate sheet, and a layer of material having a lower th...
