1. A sealed and thermally insulating tank (71) incorporated in a supporting structure (2), the tank including at least one inclined tank wall (1) forming an angle with a horizontal direction and fixed to a supporting wall of the supporting structure (2), the tank wall (1) having a multilayer structure including successively, in the direction of the thickness (52) from the outside to the inside of the tank, a thermally insulating barrier (3) held against the corresponding supporting wall and a sealed membrane (4) carried by the thermally insulating barrier (3), the tank comprising sealed or substantially sealed strips (15) in the space formed between the thermally insulating barrier (3) and the supporting wall, wherein the sealed strips (15) segment the space between the thermally insulating barrier (3) and the supporting wall in a plurality of successive zones (14) in a direction of a greatest slope (51) of the wall, the zones (14) extending over an entire transverse dimension of the tank wall (1) in a transverse direction (50) inclined relative to the direction of the greatest slope.
