Document Type and Number:
Japanese Patent JP6878771
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To impart incombustibility to a vacuum heat insulation material with a simple method without changing a spatial size of an install place.SOLUTION: A vacuum heat insulation material fundamentally comprises a casing material with a gas barrier property, and a core material subjected to decompression sealing in the casing material; and has two main surfaces opposite to each other. The casing material is configured such that laminate films having a thermal fusion layer on its single-sided surface are overlapped so that the thermal fusion layers are opposite to each other; an outer periphery of the casing material is a thermal fusion seal part; and at least one of the main surface is covered by a laminate comprising a plurality of fire-resistant films.SELECTED DRAWING: Figure 2
