PROBLEM TO BE SOLVED: To easily dissipate moisture even if water is contained in the case of using in a high temperature and high humidity atmosphere such as a concrete curing room by providing an opening at least on one metal plate of a heat insulation panel. SOLUTION: In the concrete curing room partitioned into three rooms, heat insulation panels 1 are disposed on its wall and ceiling, a laminated surface of metal plates each having an opening 11 is disposed toward outside of heated steam, and a steam tube 12 for sending steam to the curing room is connected to a boiler. A shape of the opening 11 previously formed at the plate may have all geometrical shape such as a rectangular or circular shape. And, the number of the openings may be one or a plurality. Accordingly, since the curing room can dissipate stream via the opening 11 of the plate disposed toward an outside of the curing room even if the steam is invaded into the panel 1, a decrease in heat insulation or an increase in weight can be suppressed. |
