<P>PROBLEM TO BE SOLVED: To provide a heat insulation remodeling wall which can be constructed easily and improves a heat insulation performance. <P>SOLUTION: In a vacuum heat insulation member 10 provided on an indoor-side surface of an existent wall 11 excepting a window or door frame 24, between gas barrier outer coating materials of which the heat-welded layers face each other, a plurality of core materials are disposed while being spaced apart from each other by a predetermined interval in a direction approximately vertical to a thickness direction and are sealed under reduced pressure. The outer coating materials (heat-welded layers) between the neighboring core materials are heat-welded in such a manner that the plurality of core materials are positioned within independent pressure reduction spaces, respectively. An indoor-side surface of a pierce-proof plate 13 provided at an indoor side of the vacuum heat insulation member 10 in order to protect the vacuum heat insulation member 10 is not protruded at an indoor side rather than an indoor-side surface of the frame 24. In a heat insulation remodeling wall of such a configuration, the vacuum heat insulation member 10 is unlikely to deteriorate heat insulation and a dimension of protrusion of the wall surface to the indoor side can be reduced, thereby performing simple and high-performance heat insulation remodeling over a wide applicable range without any problem. <P>COPYRIGHT: (C)2013,JPO&INPIT |
