PURPOSE: To form a non-planar molded object having proper handling characteristics and abrasion resistance from a planar panel of a granular insulating material. CONSTITUTION: A non-planar molded object of a granular insulating material is formed by compacting a substantially inorg. insoluble granular insulating material to form a flat panel. Coating materials 20, 28 comprising a solidifying component coated glass cloth or a thermoplastic material effectively containing the solidifying component are arranged within molding means 22, 26 so as to be adjacent to both surfaces of the flat panel. Subsequently, the molding means are operated so as to mold the panel into a desired non-planar shape and the solidifying component is solidified. |
