(54)	INSULATION MATERIALS FOR A VACUUM INSULATED STRUCTURE AND METHODS OF FORMING

(57) A vacuum insulated structure (10, 10a, 10b) and method of forming are provided. The vacuum insulated structure (10, 10a, 10b) includes an inner liner (30, 52, 60) and an outer wrapper (32, 54, 62) coupled to the inner liner (30, 52, 60) and defining an insulating cavity (40, 56, 64). A plurality of insulation packages (46) are disposed within the insulating cavity (40, 56, 64). Each insulation package (46) includes a first filler material (48) contained within an envelope (49). A second filler material (50) is disposed within the insulating cavity (40, 56, 64).
