ABSTRACT:
An insulating panel and shapes each having an outer, continuous membrane, an internal rigid frame, and an enclosed vacuum space. The outer continuous membrane is made up of a top membrane and a bottom membrane each having a plurality of biaxially curved, concave surface which are loaded in tension when the top or bottom membranes are exposed to ambient atmospheric pressure. Between each biaxially curved, concave surface is an arcuate path through which differential tension loadings on the adjacent biaxially curved, concave surfaces are offset, thereby reducing the structure requirements on the internal rigid frame. A second embodiment has an expansion joint means, the top or bottom membrane which enable the panel to maintain the tension stress loadings on the top and bottom surfaces when thermal contraction or expansion occurs in the top or bottom membranes, a corner shape, an inside corner shape, and a container embodiment are also disclosed herein.
