ABSTRACT OF THE DISCLOSURE The present invention relates to refrigerator cabinets and, more particularly, to a door frame structure for use with such cabinets. In contemporary refrigerated cabinets, heat is absorbed by conduction from the air outside the refrigerator and is conducted through the metallic door frame around the edge of the door and into the cold portion of the door frame which is in contact with the cold air inside the refrigerator. The present invention overcomes this defect of the prior art by providing a channel-like structural member for use as a refrigerator door frame, having a generally U-shaped cross section including a first flange, a second flange, and an intermediate central portion wherein the improvement comprises a thermally insulative thermal barrier interposed between said central portion and said second flange, and holding those portions in rigid spaced-apart relationship.
