Abstract
Method of adhesively bonding second insulating blocks to a ship's inner hull using beads of mastic for the production of a sealed, thermally insulating tank for the transportation of liquefied gases, the tank having two successive sealing barriers alternated with two insulating barriers of first and second insulating blocks produced from plywood panels and containing or carrying thermally insulating materials, the second insulating blocks of the secondary insulating barrier being fastened directly against the inner hull, the method including applying beads of mastic to the lower face of the panels of the second insulating blocks along mutually parallel lines, positioning the second insulating blocks against the inner hull, and pressing thereof against the inner hull until polymerization of the mastic, wherein at least two of the beads on the lower face of at least one panel of the second insulating blocks are arranged along wavy parallel lines.
