PROBLEM TO BE SOLVED: To provide a rigid polyurethane foam laminate which can be thinned, can be produced inexpensively, is excellent in heat shielding characteristics by retarding high temperature heat from reaching the inside side, and can surely be improved in fire preventing performance. SOLUTION: In the rigid polyurethane foam laminate having a sandwich structure, a steel sheet 1 is set on the surface side of rigid polyurethane foam 2, a back material 3 having an aluminum foil layer of 15-50μm thickness is set on the back side of the rigid polyurethane foam 2, and a slate plate 4 can be attached to the back material 3.
