PROBLEM TO BE SOLVED: To obtain a heat insulating object composed of a wall member becoming easily releasable from hard urethane foam under a specific treatment condition. SOLUTION: A heat insulating object is composed of a panel molded product 1 wherein a heat insulating object is filled into the gap between an iron panel 3 and a wall made of a plastic panel. The plastic panel is formed of an A-PET sheet 2 composed of amorphous polyethylene terephthalate and the heat insulating object is hard urethane foam 4 formed by using hydrofluorocarbon or hydrocarbon containing no chlorine in its molecule as a foaming agent. |
