The synthetic wall is composed of two sheets (2,4), the internal one (4) being plane on all of its surface. The external sheet is ribbed (6,8,10) on one part and plane on the rest of its surface. The ribs are equally divided on the sheet surface. The two sheets are fixed together on a major part of their plane surfaces. The internal sheet ribs have an upper edge (6) of dihedral section forming a spout. The ribs comprise several folds or "chimneys" (8), with there axis perpendicular to the upper edge, and several folds forming struts (10) with their axis inclined to the upper edge. All the ribs are connected in an internal space receiving a heat shaped synthetic filling material.
