A glass door for a refrigerator or freezer having an open rectangular frame around the glass, the top, bottom and sides of the frame each comprising a front metal extrusion and a rear plastic extrusion, the front extrusion having a part extending in front of the glass and the rear having a part extending in back of the glass, the extrusions being snap-fitted together with the glass between said parts, the plastic rear members being of low thermal conductivity relative to the metal front members for reduced heat transfer from the metal front members through the plastic rear members to maintain the metal front members warmer and avoid condensation of moisture on the exposed surfaces thereof.

A door for a refrigerator or freezer exposed to relatively warm ambient air, which may be humid, at one face constituting its front and to relatively cold ambient air at its other face constituting its rear, comprising: an open rectangular frame having a top, bottom and sides and a glass panel in the frame, the top, bottom and both sides of the frame each comprising a front member of metal and a rear member of plastic, the front member having a part extending in front of the glass panel and the rear member having a part extending in back of the glass panel, and means for securing said members together with the glass panel between said parts; the plastic rear members being of low thermal conductivity relative to the metal front members for reduced heat transfer from the metal front members through the plastic rear members to maintain the metal front members warmer and avoid condensation of moisture on the exposed surfaces thereof; each front member being a length of an aluminum extrusion of such transverse cross section as to have a front flange comprising the part extending in front of the glass panel, a web extending rearward from the outer margin of the front flange a distance less than the thickness of the glass panel, a rear flange extending inward from the web at the rear of the web narrower than the front flange and having its inner margin spaced outward from the edge of the glass panel, said rear flange having a lip at its inner margin curved toward the front flange, and a rib extending rearward from the rear flange, the rib being spaced inward from the web; said web and rear flange in conjunction with said front flange defining a formation for receving hinge pins at the top and bottom of one side of the door; each rear member being a length of plastic extrusion of such transverse cross section as to have a second flange providing the part extending in back of the glass panel, a rim extending forward from the outer margin of said rear member flange in interengagement with the rib of the front member, and a hook member extending forward from said rear member flange in interengagement with said rear flange of a front member, said hook member comprising a resilient flexible web extending forward from said rear flange member having a hook formation at its forward edge engageable with said curved lip, said rear member flange comprising an outer portion and an inner lip portion joined by a bridge portion with a slot between the inside edge of the outer portion and the outside edge of the inner lip portion, the hook member extending forward from the bridge portion, and a gasket being provided all around the rear of the frame having a portion extending through the slot securing it in place, the gasket being engageable with the cabinet of the refrigerator or freezer; said door having a space within the frame all around the glass panel bounded by the frame, the front flange, web and rear flange of each front member, and the hook member, the bridge portion and the inner lip portion of each rear member, said space being filled with a foamed-in-place plastic foam thermal insulation material.
