ABSTRACT:
A refrigerator door assembly comprising a plurality of insulated doors each mounted for pivotal swinging movement about a vertical axis. The insulated doors each comprise a plurality of glass panes disposed in side-by-side relation with a structural frame at least partially interposed and contained between the glass panes for maintaining the panes in parallel relation with the sealed air space therebetween and for supporting the door for swinging opening and closing movement, without the necessity for a separate outer load carrying support frame as conventionally required. Each door has a trim portion formed of a structural foam that has insulating qualities so as to eliminate the necessity for electrical heating of the door for condensation control, while at the same time enhancing the structural rigidity of the door assembly.
