1. An insulated structure for an appliance, the insulated structure comprising:
an inner liner and an outer wrapper that are attached together to define an insulating cavity therein;
a plurality of glass spheres disposed within the insulating cavity, the plurality of glass spheres defining interstitial spaces therebetween;
a coating material disposed at least partially on outer surfaces of the plurality of glass spheres, wherein the plurality of glass spheres and the coating material define an adhering base material; and
a silica-based material disposed on at least a portion of the adhering base material, wherein the coating material and the silica-based material occupy substantially all of an interstitial volume defined by the interstitial spaces.
