The multilayered body of insulating reflective materials is produced by (a) mixing diatomaceous earth powder and ceramic fiber in the ratio of 20:80-80:20, with 40-60 wt% water, for the upper layer, (b) molding this mixture in the mold coated with titanium oxide or zirconium oxide powder by vibration or compression, and drying it, (c) mixing inorganic activated stone powder and ceramic fiber in the ratio of 20:80-80:20, with 40-60 wt% water, for the lower layer, (d) molding this mixture for the lower layer into the heating pot by vibration or compression, (e) laminating over the upper layer the lower layer.
