Abstract
A three-dimensional (3D) vacuum insulation panel (VIP) and a folding approach to create the 3D VIP from a two-dimensional (2D) VIP of non-uniform thickness for a refrigerator, a refrigerator freezer or a non-appliance, are disclosed. The folding approach includes placing a VIP main panel and a plurality of VIP wall panels on an outer film, where one or more panels are of a greater thickness than other VIP panels; placing an inner film on top of the VIP main and wall panels and sealing the films together. The inner film is longer than the outer film and this allows the films and the VIP wall panels to be folded into a finished panel, wherein the longer inner film allows for fording without causing tears or micro-cracks in the film that would adversely affect the insulation properties of the three-dimensional (3D) VIP.
