Abstract
The invention relates to a thermally insulating composite wall for any kind of tank on ships or on land. The wall comprises a self-supporting external wall, a bed of thermally insulating elements secured to said wall at least partially by means of a hardened packing material and a fluid-tight internal lining; said material may notably be a cellular material in contact with all the external surface of this bed and obtained by in situ expansion and subsequent hardening of a deformable product capable of spontaneous expansion which has been previously placed according to a discontinuous distribution.
