The present invention relates to an insulation system for a liquefied gas storage tank for insulating a liquefied gas stored inside a tank body, comprising: a sheet part fixedly installed on a tank body; an insulating part for forming a plurality of insulating layers by spraying and stacking foam on the sheet part; and a reinforcing layer in a form of a mesh provided between the plurality of insulating layers. An object of the present invention is to provide the insulation system for a liquefied gas storage tank and a construction method thereof that can prevent damage to the insulation system due to a difference in thermal expansion coefficient between an outer wall of a storage tank and a foam in a cryogenic environment and maintain the insulation performance of the insulation system.
