Abstract: A vacuum insulated refrigerator structure being formed from a wrapper extending around a liner is provided. The liner is positioned inside of the wrapper to form a gap there between, and to form a cavity between the wrapper and the liner. An insulating thermal bridge is formed from molding one or more extruded rails to one or more corner pieces in an injection molding device. The insulating thermal bridge is coupled across the gap wherein the insulating thermal bridge includes elongated first and second channels wherein the first and second edges are inserted into the elongated first and second channels, respectively. A curable sealant is contacted to the elongated first and second channels and the cavity is at least partially filled with a porous material between the wrapper and the liner. A vacuum is formed in the cavity and the cavity is sealed to maintain the vacuum.
