PURPOSE:To change heat insulation performance according to a temperature change by a method wherein panels formed such that a heat insulating substance and a heat transfer substance are alternately arranged are slidably superposed with each other to form a heat insulation panel. CONSTITUTION:Panels 2 formed such that a heat insulating material 3, such as foamed urea resin, rigid foamed polystyrene, and rigid polyethylene, and a heat transfer substance 4, such as glass, ceramics, and a metal, are alternately arranged are slidably superposed with each other. When heat insulation performance of the heat insulating panel 1 is reduced, the heat insulating substances 3 or the heat transfer substances 4 are superposed with each other and heat is easily transferred through the heat transfer substances 4. Further, when heat insulation performance is increased, the panels 2 are slid with the aid of a hydraulic cylinder 7 to superpose the heat insulating substance 3 with the heat transfer substance 4, and heat is made hard to transfer. Thus, through slide of the panels, heat insulating performance is freely changed. |
