Abstract
A refrigeration apparatus enclosure and method of forming the same wherein an inner laminate wall is provided in an outer cabinet for providing the sheet liner and insulation portions of the refrigeration apparatus enclosure. The laminate wall is folded along lines cut through the insulation to conform to the configuration of the outer cabinet and insulation is provided for filling the resultant voids to complete the enclosure construction. The voids are filled by foamed-in-place plastic which may further serve to bond the laminate wall to the outer cabinet. The rear wall of the cabinet may comprise a flat laminate wall and a divider wall may be provided within the cabinet for dividing the space therein into separate compartments. The divider wall may comprise another laminate wall.
