A noncombustible inorganic insulating material is provided to increase insulating performance and to reduce the weight of the insulating material by agitating water glass, fire retardants, and antimone. An inorganic foam vaporizes crystal water by heating glass rock at 870 to 900°C with CO2 rapidly. An auxiliary material, which is formed by agitating water glass, fire retardants, and antimone, is added and molded at the mold. The mixed ratio between the inorganic foam and the auxiliary material is 2:1. The auxiliary material is agitated with the ratio of 60 to 70 weight% of the water glass, 27.5 to 32.5 weight% of the fire retardants, and 2.5 to 3.5 weight% of the antimone.
