Disclosed is an insulation system for a liquefied gas storage tank having a double metal barrier structure. According to the present invention, the insulation system for a liquefied gas storage tank comprises: a main insulating wall having a multi-layer structure divided into at least two layers including an upper heat insulating layer and a lower heat insulating layer; an auxiliary insulating wall which is installed on top of the main insulating wall and consists of a plurality of auxiliary insulating panels spaced apart at regular intervals; a secondary sealing wall installed on top of the auxiliary insulating wall; a primary sealing wall installed on the upper side of the secondary sealing wall; and a sealing wall spacing layer interposed between the secondary sealing wall and the primary sealing wall to space the primary sealing wall from the secondary sealing wall. The primary sealing wall and the secondary sealing wall include a plurality of corrugations formed in the transverse and longitudinal directions to absorb heat shrinkage caused by cryogenic temperatures. The corrugations formed on the primary sealing wall protrude toward the inside of the storage tank, and the corrugations formed on the secondary sealing wall protrude toward the outside of the storage tank and are accommodated in the gap between the auxiliary insulating panels.
