Disclosed is an insulation system for a liquefied gas storage tank. According to the present invention, the insulation system for a liquefied gas storage tank comprises: an insulating wall including polyurethane foam or reinforced polyurethane foam insulation; a secondary sealing wall made of a composite material that is installed on top of the insulating wall; a plywood layer installed on top of the secondary sealing wall; and a primary sealing wall installed on top of the plywood layer. The secondary sealing wall is installed at the top level of the insulating wall rather than in the middle of the insulating wall. Accordingly, there is the effect of eliminating the concern about leakage of the secondary sealing wall and advantage effects in terms of constructability and economics.
