An objective of the present invention is to provide a membrane-type liquefied gas insulation system capable of securing better performance than a conventional technique in the aspect of both insulation and airtightness. The membrane-type liquefied gas insulation system of a double metal barrier structure has a double sealing structure in which a secondary insulation layer, a secondary membrane, a primary insulation layer, and a primary membrane are sequentially stacked from an inner wall of a storage container toward the inside of the storage container and comprises: a plurality of secondary insulation panels continuously arranged on the inner wall of the storage container to make up the secondary insulation layer; and a plurality of primary insulation panels continuously arranged on the secondary membrane to make up the primary insulation layer. The secondary insulation panels and the primary insulation panels are manufactured to have the same length and width to be cross-arranged such that the vertex portions of the primary insulation panels are positioned in the middle of the secondary insulation panels. The secondary membrane includes a plurality of wrinkles formed in the lateral and longitudinal directions of the storage container. The wrinkles formed on the secondary membrane are formed to protrude toward the outside of the storage container to be accommodated in a space between the secondary insulation panels arranged next to each other.

    저장용기의 내벽면으로부터 저장용기의 내측 방향으로 2차 단열층, 2차 멤브레인, 1차 단열층 및 1차 멤브레인이 순차 적층되는 이중 밀봉 구조를 가지는 멤브레인형 액화가스 단열시스템에 있어서, 저장용기의 내벽면 상에 다수개가 연속적으로 배치되어 2차 단열층을 구성하는 2차 단열패널; 및 2차 멤브레인 상에 다수개가 연속적으로 배치되어 1차 단열층을 구성하는 1차 단열패널을 포함하고, 2차 단열패널과 1차 단열패널은 길이와 폭이 모두 동일하게 제작되어 1차 단열패널의 꼭짓점 부위가 2차 단열패널의 중심에 위치하도록 서로 교차 배치되며, 2차 멤브레인은 저장용기의 횡방향 및 종방향을 따라 형성되는 다수의 주름을 포함하되, 2차 멤브레인에 형성되는 주름은 저장용기의 외측 방향을 향하여 돌출되도록 형성되어 서로 이웃하게 배치되는 2차 단열패널 사이의 공간부에 수용되는 것을 특징으로 하는, 이중 금속 방벽 구조의 멤브레인형 액화가스 단열시스템이 개시된다.
