Abstract:
A method of forming an insulated structure for an appliance includes forming a structural enclosure having an outer wrapper and an inner liner and an insulating cavity defined therebetween, forming an insulating powder material, compacting the insulating powder material to form a pre-densified core material, disposing the pre-densified core material within an insulating cavity, wherein the insulating cavity is defined between the outer wrapper and the inner liner and expressing at least a portion of the gas contained within the insulating cavity, wherein the insulating cavity is hermetically sealed to define a vacuum insulated structure.
