Abstract: A refrigerator cabinet having a transverse partition for dividing the cabinet into an upper freezer compartment and a lower food storage compartment. The partition includes a composite insulation separator and drain trough structure in the form of a molded moisture impervious sealed plastic separator shell completely filled with unfused pre-expanded polystyrene contacting beads, each of the beads being substantially spherical in shape and having a diameter of the order of 0.060 to 0.100 inches whereby convection heat transfer between the upper and lower shell walls is obviated.
