PROBLEM TO BE SOLVED: To provide a laminate capable of realizing excellent energy saving which is used as a building material and a heat insulating material.SOLUTION: There is provided a laminate obtained by laminating a surface layer 1-1 having a thickness of 3-15 mm which has through holes with a size of 1-10 mm with respect to the thickness direction and a heat storage layer 2-1 having a thickness of 1-10 mm. There is provided a laminate in which the heat storage layer is obtained by laminating two or more heat storage layers having different phase change temperature. There is provided a laminate having through holes with a size of 1-10 mm with respect to the thickness direction in which a metal layer is laminated on one surface or both surfaces of a heat storage layer. There is provided a laminate in which an aliphatic hydrocarbon having 8-36 carbon atoms, a long chain alcohol having 8-36 carbon atoms, a long chain fatty acid having 8-36 carbon atoms and a long chain fatty acid ester having 8-36 carbon atoms are preferably used as a heat storage material.SELECTED DRAWING: Figure 1 |
