PURPOSE: A sheet for the barrier of an LNG cargo and an insulation structure of an LNG cargo using the same are provided to reduce the adhesion failure of a secondary barrier by forming the secondary barrier using the sheet having fine holes. CONSTITUTION: A sheet for the barrier of an LNG cargo comprises a porous sheet body (100) composed of a first metal foil layer (101), a glass fiber layer (102), and a second metal foil layer (103). The glass fiber layer is integrally formed between the first and second metal foil layers. The porous sheet body comprises a sheet intermediate area (110) and sheet edge areas (111,112). The sheet intermediate area covers the top of the gap between lower insulation panels. The sheet edge areas are formed on both sides of the sheet intermediate area and have multiple fine holes (120). |
