ABSTRACT:
A method of assembling a refrigerator having a fresh food compartment and a freezer compartment separated by a mullion partition, the refrigerator having an outer metal casing with side walls, an inner liner and foamed-in-place thermal insulation between the metal casing and liner wherein the insulation has a void cavity adjacent the mullion partition. The metal casing is formed to have a vertical front face perpendicular to the side walls and a reinforcing nut strip is placed in the front face. The front face and nut strip aligned screw receiving apertures. A nozzle is inserted through the aligned apertures into the insulation void cavity and foamable hot melt material is forced through the nozzle into the insulation void cavity to fill the cavity. The nozzle is then withdrawn from the aligned apertures and a fastener is secured through the aligned apertures.
