A refrigeration cabinet comprising heat conducting elements, including a box-like inner liner and a plurality of lengths of interconnected refrigeration tubing extending along a plurality of outer wall surfaces of the liner and in heat conducting relation by direct contact with said wall surfaces, an outer shell in spaced relationship to the inner liner, a first layer of insulating foam, having been foamed in place, covering at least portions of said lengths of tubing and covering and adhering to areas of the liner outer wall surfaces between adjacent lengths of said tubing, said layer covering sufficiently large areas of said wall surfaces and sufficient portions of said lengths of tubing and having sufficient rigidity to serve as the sole means securing and maintaining said tubing in heat conducting relationship with said wall surfaces but being of less thickness than the space between said inner and outer shell, and a second layer of insulating foam compatible with the foam of said first layer, said second foam layer having been foamed in place over the first layer and filling the space between said outer shell and said first foam layer and any portions of said tubing and wall surfaces not covered by said first layer, said first and second layers of foam each having a thermal conductivity coefficient representative of rigid insulating foam whereby together they provide heat insulation throughout substantially the entire space between said wall surfaces and tubing and said outer shell.
