VACUUM HEAT INSULATING MATERIAL, VACUUM HEAT INSULATING MATERIAL APPLIED HEAT INSULATED WALL, WALL OF BUILDING, AND HOT WATER STORAGE TANK

摘要

PPROBLEM TO BE SOLVED: To provide a vacuum heat insulating material constituted by covering a plurality of core members with a covering member having gas barrier property and arranging the core members in spaces being independent from each other to improve thermal insulation performance. PSOLUTION: In this vacuum heat insulating material 14 constituted by covering a plurality of core members 15 with the covering member 16 having gas barrier property, arranging a plurality of core members 15 in the independent spaces by reducing pressure in the inside and sealing it, and providing a non-core member part 17 composed of only the covering member 16 between the core members 15, area of the non-core member part 17 having no thermal insulation performance is reduced as much as possible by bending the non-core member part 17 and narrowing an interval between the core members 15 to improve thermal insulation performance. In addition, it is possible to realize a heat insulated wall having excellent thermal insulation performance by applying this vacuum heat insulating material. PCOPYRIGHT: (C)2007,JPO&INPIT
