The gas impermeable wall shall find application in building of cold storage chambers subjected to vibrations, such as ship cold store premises. It has elastic protection against vibrations, controllabel cable run of the electrical installation and it economizes the material required for covering over the joint and for the rigidity of the connection. The wall is made of a panel connected in the groove and tongue system, groove (1) being one-quarter of a circumference, and tooth (2) is semicircular (3), and at least half of it belongs to the groove. The surface layer (5) of the groove (1) is doubled, and at the semicircuit (3) it finishes as an end (6) parallel to the doubled surface layer (7), and an elastic body (9) is fitted continuously between them and seat (8) of the semicircuit (3). After making the groove and tongue fit, the lining layer (10) covers the fit and the electrical installations (11). The internal edges (13) of sides (14) are also a quarter of a circumference in length./!
