Abstract: An appliance includes an outer wrapper, an inner liner, a trim breaker having a wrapper channel that receives a wrapper edge of the outer wrapper and a liner channel that receives a liner edge of the inner liner, and an insulation material disposed within an insulating cavity defined therebetween. A multi-component thermal encapsulation material defines pre-mix, application and sealing states. The pre-mix state is defined by the distinct components of the thermal encapsulation material being separated from one another, the application state defined by the distinct components combined together into an uncured state of the thermal encapsulation material, and the sealing state defined by the thermal encapsulation material disposed within the wrapper and liner channels and surrounding the wrapper and liner edges, respectively, in the sealing state that defines a hermetic seal between the trim breaker and the outer wrapper and the inner liner.

Abstract: A vacuum insulated appliance structure, comprising: a first layer of a first polymer material. A second layer of a second polymer material is molded to (e.g. over) at least a portion of the first layer, and a third layer of a third polymer material is molded to (e.g. over) at least a portion of the second layer to form a first component. At least one of the layers is impervious to one or more gasses. One or more additional components are secured to the first component to form a vacuum cavity. The vacuum cavity is filled with a porous material, and the vacuum cavity is evacuated to form a vacuum.

Abstract: A method of forming an insulated door panel includes folding side flanges of a metallic sheet to define side edges of a structural outer panel that extend from a front panel. A gap is defined between each set of adjacent side edges. Interior blocks are secured to an interior of the structural outer panel proximate each gap to define adhesive cavities. Exterior blocks are positioned at an exterior surface of the structural outer panel at each gap to further define the adhesive cavities. An adhesive is disposed within each adhesive cavity and is contained therein by the interior and exterior blocks. The adhesive is cured to a solid sealing member that adheres the interior blocks to the interior surface of the structural outer panel to form a sealed structural panel. The exterior blocks are removed and each solid sealing member defines a hermetic seal at each gap.
