Beschreibung
Zusammenfassung:	An appliance cabinet includes a structural envelope having an exterior surface and an interior surface that defines an insulating cavity, wherein the insulating cavity defines an at least partial vacuum. A plurality of silica-based agglomerates are disposed within the insulating cavity, wherein each agglomerate of the plurality of silica-based agglomerates includes silica-based powder insulation material that is water-densified and is at least substantially free of a material binder. A secondary insulation material is disposed within interstitial spaces defined between the plurality of silica-based agglomerates, wherein the plurality of silica-based agglomerates defines an interior structure that resists inward compressive forces exerted as a result of the at least partial vacuum defined within the insulating cavity.
