A refrigerator door assembly having a thermally efficient door mounting frame which includes a forward structural frame member mounted within the opening of a refrigerator cabinet for providing an attractive finished appearance for the frame, a separate rear structural frame member for establishing a door closure sealing surface against which doors of the assembly close and which may be made of less expensive and/or less heat conductive material than the forward structural frame member, and a flexible plastic barrier sheet interposed between the forward and rear structural members for thermally insulating the structural members from each other. Stitch like connections are formed from adjacent connecting flanges of the forward and rear structural members together without substantial contact therebetween. Various magnetically attractable sealing strip arrangements are disclosed that are adapted for use in low temperature refrigeration units without condensation or frost build up.

A refrigerator door assembly mountable in an opening in the wall of a refrigerator cabinet comprising a door mounting frame, at least one insulated door mounted on said frame for pivotable movement between open and closed positions relative to said mounting frame, said door including an insulated glass unit having a plurality of glass panes mounted in spaced apart relation to each other with an air insulating space therebetween, means on said door and mounting frame for defining a pair of parallel, spaced-apart gasket seals between said door and mounting frame when said door is in a closed position, said gasket seals defining means including first and second gaskets mounted on one of said door and mounting frame and means defining respective sealing surfaces on the other of said door and mounting frame for engagement by said first and second gaskets when said door is in a closed position, and said first gasket being a magnetic gasket and said second gasket being a compression gasket, said compression gasket being disposed in outwardly spaced relation to said magnetic gasket when said door is in a closed position for blocking communication of ambient air to said magnetic gasket when said door is in a closed position.
