A method (300) for manufacturing an insulation member (10) for an appliance (40) includes steps of forming (302) a porous bag (14) with a woven fabric, filling (310) the porous bag (14) with insulation materials (18), heat sealing (312, 314) the porous bag (14), vibrating (318, 322) the porous bag (14) to define (324) a pillow (20), compressing (328, 332, 334, 336) the pillow (20) within a mold to define (330) a compressed insulation member or panel (24), and evacuating (348) the compressed insulation member or panel (24) within an insulated structure to define (352) a vacuum insulated structure (12).
