製造方法。3. A heat insulation consisting of a plurality of foaming heat insulating materials between an inner plate and an outer plate forming an exterior of a heat insulating wall by at least one partition plate partitioning the inner plate and the outer plate in the thickness direction. In a method for manufacturing a multi-layer heat insulating wall for forming layers, an insertion hole for a heat insulating material injection nozzle is provided in the inner plate or the outer plate, and the partition plate communicates each gap formed by the partition plate with the insertion hole. A nozzle insertion hole is provided, the nozzle is inserted into the farthest gap from the nozzle insertion side, the heat insulating material is injected and foamed, and then the tip position of the nozzle is sequentially moved to the gap near the nozzle insertion side to perform the injection foaming. Method for manufacturing multi-layered heat insulating wall.
