An asbestos free, calcium silicate insulating material suitable for use in the casting of molten non-ferrous metals, and suitable for use in applications where a fire resistant, heat insulating, electrical insulating, and corrosion resistant material is desirable. The calcium silicate insulating material is produced by combining lime, a siliceous component, alumina silica microspheres, wollastonite and organic fibrous material in the presence of water to form a slurry. The slurry is then placed under steam pressure, to react the lime, siliceous component and water, dried, and heat treated if necessary.
