It is assumed that the studs are stored and the ears are fixed to the found surface of the base material. This is the same construction form as when a film-wrapped fiber-based heat insulating material (glass wool, rock wool, etc.) is installed between the joists under the floor or between the studs under the wall.

However, since the latent heat storage material is much heavier than the fiber-based heat insulating material, the film that wraps it also needs to be strong, and the thickness of the selvage portion to which the film is welded increases accordingly. Therefore, as shown in FIG. 8, when the selvage portions 4 of the heat storage bodies 1 adjacent to each other across the base material 5 are overlapped on the found surface of the base material 5, the finishing material 6 stretched on the selvage material 6 There is a possibility that unevenness may occur on the surface of the selvage portion 4 due to the overlapping thickness of the selvage portion 4.
