The frame unit 10 is not limited to the one assembled at the installation location of the unit house 1, and may be assembled in advance at an appropriate location and carried into the installation location.
Then, the floor side heat insulating material 3, the floor base material 4, and the floor finishing material 5 are constructed, the heat insulating wall panels 20, 20A to 20F are constructed, and the heat insulating ceiling panel 6, the ceiling side heat insulating material 7, the roof material, etc. are constructed. You may try to do it. Further, the corner member 17, the peripheral edge 18, and the like may be constructed. The above construction procedure is only an example, and various modifications are possible. Further, the unit house 1 may have a structure that can be disassembled (disassembled) and reassembled.

Further, in the present embodiment, an example in which the wiring box 28 and the tubular member 27 are embedded in at least one of the plurality of heat insulating wall panels 20, 20A to 20F constituting the unit house 1 is shown. However, it is not limited to such an aspect. For example, the wiring box 28 and the tubular member 27 may not be embedded. In this case, the accommodating groove 25 of the tubular member 27 and the box accommodating recess 26 of the wiring box 28 may not be provided in the rigid foam resin base material 21A.

Further, in the present embodiment, an example in which the heat insulating ceiling panel 6 and the floor side heat insulating material 3 are provided in the unit house 1 is shown, but one or both of these may not be provided.
Further, in the present embodiment, an example in which the upper frame 11, the lower frame 13, and the vertical frame 14 are provided in the unit house 1 is shown, but at least one or all of these is not provided. May be good. In this case, an appropriate base material or the like for holding each end of the heat insulating wall panels 20, 20A to 20F may be provided.
Further, in the present embodiment, an example in which the heat insulating wall panels 20, 20A to 20F constitute the unit house 1 is shown, but the present invention is not limited to such an embodiment. The heat insulating wall panels 20, 20A to 20F according to the present embodiment are not limited to the unit house 1, and can be used as walls of various buildings. Further, the configuration of each member and each part used in the heat insulating wall panels 20, 20A to 20F according to the present embodiment is not limited to the above-described embodiment, and various other modifications are possible.
