BUILDING COMPOSITE HEAT INSULATION PANEL AND ATTACHMENT STRUCTURE OF BUILDING COMPOSITE HEAT INSULATION PANEL

摘要

PROBLEM TO BE SOLVED: To provide a building composite heat insulation panel which can sufficiently suppress the temporal deterioration of heat insulation performance, and an attachment structure of the composite heat insulation panel.SOLUTION: A building composite heat insulation panel comprises: one or a plurality of vacuum heat insulation materials; a hard foam body which surrounds the one or a plurality of vacuum heat insulation materials into a single plate shape; and a gas barrier layer which is laminated on at least one surface of the hard foam body. It is preferable that the gas barrier layer is laminated on both surfaces of the hard foam body. It is preferable that the gas barrier layer has at least a metal layer. It is preferable that the gas barrier layer has a resin layer which is laminated on one face side of the metal layer. It is preferable that a main component of the metal layer is aluminum. It is preferable that the gas barrier layer has seams. It is preferable that the seams are formed in an annular shape.
