PURPOSE:To display the effect of heat insulation, waterproofness and sound absorption sufficiently, and to simplify the execution of work. CONSTITUTION:A synthetic resin foam 6 having a fitting section 6 in the same shape as the recessed section 4b of a metallic roof 4 and made higher than the projecting section 4a of the metallic roof 4 is fitted and bonded into the recessed section 4b of the metallic roof 4. Space 8 surrounded by the projecting section 4a of the metallic roof 4 and the synthetic resin foams 6 is impregnated with a foamed polyurethane stock solution, and a foamed urethane layer 9 whose top face is flush with the top faces of the synthetic resin foams 6 is formed. Lastly, a waterproof sheet member 10 is abutted and bonded to the top faces of the synthetic resin foams 6 and the foamed urethane layers 9. The heat insulation, waterproofness and sound absorption are displayed sufficiently by the synthetic resin foams 6, the foamed urethane layers 9 and the waterproof sheet member 10. |
