Method for manufacturing a wall of a sealed and thermally insulating tank having inter-panel insulating inserts

The invention relates to a method for manufacturing a sealed and thermally insulating tank wall comprising:providing a thermally insulating barrier comprising two insulating panels delimiting an inter-panel space,providing an insulating insert comprising a wrapper completely covering an insulating core,inserting a suction nozzle of a suction system into the insulating insert through an orifice in the wrapper,applying a vacuum pressure in the insulating insert so as to reduce the thickness of the insulating insert through vacuum pressure,inserting the insulating insert into the inter-panel space while maintaining the suction of the suction system,when the insulating insert has been inserted into the inter-panel space, removing the suction nozzle from the insulating insert.
