PROBLEM TO BE SOLVED: To provide a thermal insulating material capable of sufficiently protecting the end face against ultraviolet rays or water, its construction method and structure. SOLUTION: A metal siding 10 is formed by interposing the thermal insulating material 12 between a pair of metal plates 11 and 11. A gap of about 5 to 20 mm is formed between the metal sidings 10. The end face 12a of the thermal insulating material 12 of the metal siding 10 facing the gap is a coarse face with a large number of holes having a depth as deep as 30 to 600μm and formed in a hole density of 50 to 700 pieces/cm<SP>2</SP>. A back-up material 3 consisting of foamed polyethylene and foamed EPDM, etc. is pressed into the gap between the metal sidings 10, and the front side is filled with a sealing compound 4 consisting of a modified silicone resin, epoxy modified urethane, etc. COPYRIGHT: (C)2006,JPO&NCIPI
