ABSTRACT:
A method of forming an insulated cabinet wall structure wherein a body of insulation is foamed in situ against an outer face of a liner sheet strip to define a laminate. A plurality of holes are formed in the laminate extending through the liner and into the insulation, and a plurality of supports are installed on the laminate by insertion of a mounting portion thereof in the mounting holes. The laminate with the supports secured thereto is subsequently formed into a preselected cabinet configuration to define a chamber with the supports projecting inwardly from the liner into the chamber. This structure may then be inserted into a formed outer cabinet.
