A method of forming a vacuum insulated refrigerator cabinet, the method comprising providing first and second sheets of material. The first sheet of material is thermoformed over a first forming tool forming a first intermediate structure. The first intermediate structure is then thermoformed over a second forming mold to create a second intermediate structure. The second sheet of material is then sealing connected with the second intermediate structure forming an annular space. A vacuum is created in the annular space creating a vacuum insulated cabinet...
