Abstract
A refrigerator door assembly comprising a plurality of insulated glass doors mounted in a cabinet frame for relative movement. The glass doors each includes an insulated glass unit having a plurality of glass panes disposed in side-by-side relation, a metal spacer interposed between adjacent of the panes for maintaining the panes in parallel relation with an air space therebetween, and a sealant about the periphery of the spacer for sealing the air space from the outside environment. An outer metal frame is disposed about the periphery of the glass unit, and rigid, non-metallic barrier members are interposed between the outer metal frame and the glass unit for retaining the glass unit within the outer metal frame and for forming a thermal insulating barrier between the outer metal frame and the glass unit and between the outer metal frame and the cabinet frame.
