Abstract (en)
The panel comprises a reinforcement frame (2) substantially constituted by at least two longitudinal profiled elements (3a, 3b) and two transverse ones (4a, 4b) which perimetrically delimit the panel. The profiled elements are fixed in two concrete layers (7, 8) which constitute the two larger faces of the panel and are mutually spaced so as to define an interspace which accomodates the thermally insulating or lightening material layer (9).
