An appliance includes an outer shell and an inner shell, wherein the outer shell and the inner shell are engaged to define an insulating cavity therebetween, and wherein the inner shell includes an inner surface that defines an interior cavity. An insulation member includes a plurality of layers, each layer of the plurality of layers including an insulative sheet defining first and second surfaces and a plurality of microspheres at least partially disposed within the insulative sheet, wherein at least a portion of the plurality of microspheres extends outward from each of the first and second surfaces to define a plurality of protrusions, and wherein the engagement of two adjacent layers of the plurality of layers causes a portion of the plurality of protrusions to engage and define a plurality of insulating air pockets between the adjacent layers.

1. A multilayer insulation member for an appliance, the insulation member comprising: a plurality of microsphere sheets disposed in a layered configuration, wherein each microsphere sheet includes a plurality of microspheres disposed in a layer of a flexible base material, wherein at least a portion of the plurality of microspheres extends outward from the flexible base material to define first and second sets of microsphere protrusions on first and second sides of the flexible base material, wherein the first set of microsphere protrusions of a first microsphere sheet of the plurality of microsphere sheets engages the second set of microsphere protrusions of an adjacent microsphere sheet of the plurality of microsphere sheets to define a plurality of insulative air pockets defined between the first and adjacent microsphere sheets, and wherein the flexible base material is a silicone sheet. 2. The multilayer insulation member of claim 1, wherein the plurality of microsphere sheets are held in the layered configuration through surface adhesion and the microsphere sheets are free of the use of adhesives. 3. The multilayer insulation member of claim 1, wherein each microsphere sheet has a sheet thickness substantially equal to a microsphere thickness of a single microsphere, and wherein the flexible base material has a material thickness that is less than the microsphere thickness. 4. The multilayer insulation member of claim 1, wherein the plurality of microspheres are glass microspheres. 5. The multilayer insulation member of claim 1, wherein the plurality of microspheres within each microsphere sheet is disposed in an irregular configuration, wherein the irregular configuration of the plurality of microspheres defines the plurality of insulative air pockets in a substantially irregular air pocket configuration. 6.
