く向上する。<Function> In the present invention, a thin high-density foam layer is laminated and integrally bonded to a thick low-density foam layer to form a rigid foam, so the desired heat insulation effect is achieved by the large thickness of the low-density foam layer. However, the presence of a high-strength, high-density foam layer provides sufficient strength for concrete pouring. In particular, because the high-density foam layer and the low-density foam layer are laminated together during the reaction between their materials, the strength of the entire foam is significantly improved compared to when both foams are laminated after the reaction is complete. do.

Even if the foam has a higher density than the material foam, it has a thinner wall, so the cost of the rigid foam as a whole can be lowered. Therefore, the insulated boat that also serves as a formwork according to the present invention is economically advantageous.
