Here, the thickness of the side portion of each composite heat-insulating waterproof sheet 120 becomes thinner toward the end portion. Particularly, the thickness of one side portion of both side portions of the composite heat-insulating waterproof sheet 120 becomes thinner toward the end portion of the upper surface, and becomes thinner toward the end portion of the lower surface of the opposite side surface portion.

At this time, the steps formed on both side portions of the composite heat insulating waterproof sheet 120 are made such that the portions removed in the thickness direction in the left side portion and the remaining portions in the right side portion coincide with each other. Thus, when both side edges of the two composite heat insulating waterproof sheets 120 are brought into contact with and joined to each other, the thickness of the portion remaining on the right side portion of the first composite heat insulating waterproof sheet and the thickness of the portion remaining on the left side surface of the second composite heat insulating waterproof sheet It is important that the sum of the thicknesses is the same as the total thickness and is combined at the stepped portion so as to be the same as the laminated arrangement of the entire laminated array at the stepped portion.

As a result, even if two steps are adhered to both side surfaces of the composite heat insulating waterproof sheet 120, the same thickness as the whole can be maintained, and the same lamination (aluminum layer and PET layer) as the whole can be maintained.

FIG. 6 is an exemplary view showing a shape in which the side end portions of the multilayer composite heat insulating waterproof sheet according to the embodiment of the present invention and the side end portions thereof are overlapped and connected.

Referring to FIG. 6, in the present invention, when two multi-layer composite heat insulating waterproof sheets 120 are connected to each other, both sides are brought into close contact with each other, and then the reinforcing mesh 150 and the reinforcing member 160 ).

Here, the surfaces of the both side surfaces 121a and 121b whose thicknesses are reduced are opposite to each other. That is, the thickness of the first side portion 121a is thinner toward the end portion of the first side portion 121a, and the thickness of the second side portion 121b of the opposite side becomes thinner toward the end portion. Of course, the opposite case is possible. In this case, the thicknesses of the first and second side portions 121a and 121b are preferably the same.
