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.

1. A door assembly for an appliance, the door assembly comprising: a door panel including a door flange on opposite sides of the door panel;a top end cap mounted to the top of the door panel between the door flange;a bottom end cap positioned opposite the top end cap;a folded vacuum insulation panel disposed inside the door panel;an inner door liner attached to the door panel, wherein the folded vacuum insulation panel is disposed between the door panel and the inner door liner;a gasket coupled to a periphery of the inner door liner, wherein the folded vacuum insulation panel includes walls of differing thickness; anda door dyke positioned proximate the gasket, wherein the door dyke defines a thermal barrier between the inner door liner and the gasket, wherein the vacuum insulation panel at least partially occupies the door dyke. 2. The door assembly of claim 1, wherein left and right brackets are secured to an inside of the inner door liner and wherein the door assembly defines a drawer panel of the appliance. 3. The door assembly of claim 2, wherein the vacuum insulation panel at least partially fills an area proximate the inner door liner where the left and right brackets attach to the inner door liner. 4. The door assembly of claim 1, wherein top and bottom brackets are secured to one of the door panel and the inner door liner, and wherein the door assembly defines a freezer door of the appliance. 5. The door assembly of claim 1, wherein the vacuum insulation panel includes top, bottom, left and right walls that each define the walls of differing thickness of the vacuum insulation panel. 6. The door assembly of claim 5, wherein each of the top, bottom, left and right walls includes a stepped portion, each stepped portion at least partially occupying the door dyke. 7. A door assembly for an appliance, the door assembly comprising: an outer door panel;an inner door liner that is coupled to the outer door panel to define an insulating cavity therebetween;a folded vacuum insulation panel having top, bottom, left and right walls that are folded onto a main wall to define walls of differing thickness of the vacuum insulation panel; anda gasket coupled to a periphery of the inner door liner, wherein the folded vacuum insulation panel includes walls of differing thickness, wherein the inner door liner defines an internal thermal dyke proximate the gasket, the vacuum insulation panel at least partially occupies the internal thermal dyke. 8. The door assembly of claim 7, wherein each of the top, bottom, left and right walls includes a stepped portion, each stepped portion at least partially occupying the internal thermal dyke. 9. The door assembly of claim 7, wherein the vacuum insulation panel includes a continuous film structure that includes an outer film and an inner film, the inner film being larger than the outer film, and wherein the inner film defines folding areas wherein the top, bottom, left and right walls are folded to engage the main wall.
