Since the thermal conductivity is extremely high, the nail itself becomes a medium for transmitting heat, which causes condensation and the like, and also causes deterioration in performance in terms of the heat insulating effect. Also, since the heat insulating material is soft, it is necessary to interpose a patch plate between the nail and the heat insulating material in order to fix the heat insulating material with an iron nail. Due to the thickness, it becomes an obstacle and it becomes difficult to stack two or more heat insulating materials.
