Abstract
A method for manufacturing a vacuum insulated structure includes positioning an inner liner within an external wrapper and defining a gap between the inner liner and the external wrapper, drawing a vacuum to seal the gap, and injecting a first insulator into the gap. The method further includes positioning a filter proximate to the first insulator within the gap and injecting a second insulator into the gap proximate to the filter.
