Disclosed is an insulation system of a membrane type storage tank. The present invention includes: a first sealing wall directly coming in contact with cryogenic liquefied natural gas in a storage tank; a first insulation panel provided on the outside of the first sealing wall; a second sealing wall provided on the outside of the first insulation panel; a second insulation panel provided on the outside of the second sealing wall and fixed to an inner wall of a hull; and a securing device fixing the first insulation panel and the second insulation panel to each other, wherein the first insulation panel has a plurality of lower slits on a lower portion with a predetermined interval and is divided into a plurality of lower parts respectively independently generating thermal contraction. The second insulation panel has a plurality of upper slits on an upper potion with a predetermined interval and is divided into a plurality of upper parts respectively independently generating thermal contraction. A center line formed on the center of the lower part and a center line formed on the center of the upper part correspond to each other.
