Disclosed is a vacuum insulation panel having excellent thermal insulation and cold retention performance using conventional glass fibers. The vacuum insulation panel employs annealed binderless glass fibers as a core material, thus ensuring superior thermal insulation performance and preventing out-gassing in a vacuum due to the absence of organic residues in the fibers, and thereby a vacuum level of the vacuum insulation panel can be maintained for a long period of time.
