HIGH TEMPERATURE VACUUM INSULATION PANEL

摘要

The present invention relates to a vacuum insulation panel comprising a core material, and a shell material, and more specifically, to a high temperature vacuum insulation panel usable in a high temperature range. The present invention provides a high temperature vacuum insulation panel including: an inorganic core material comprising glass fiber; and a shell material for sealing the inorganic core material in which the shell material comprises a composite film including a thermal deposition layer adhered to the surface of the inorganic core material, a protective layer for absorbing and dispersing external impact, and a barrier layer for blocking the permeation of gas or moisture between the thermal deposition layer and the protective layer.
