Abstract: An insulative cabinet construction having a shell portion formed of a plurality of panels having securing portions interlocked in secured relationship. A liner is spaced inwardly of the shell structure, and foamed-in-place insulation is formed between the shell structure and liner so as to be adhered to the shell structure and liner and effectively embed the securing portions of the shell to maintain the interlocked secured relationship thereof. The interlocked portions of the shell may be crimped portions, staked portions, or stamped-together portions, as desired. The shell panels may include flanges on edge portions to provide column strength at the corners of the cabinet. The shell panels may be prefinished. Preformed closure means are provided extending between the liner and shell structure outwardly of the insulation.
