The invention relates to a factory prefabrication method for hollow panels for the on-site erection of insulated constructions. This method employs a three-dimensional framework 1 composed of thrust bars arranged in two parallel planes and of link bars linking the former. The method consists in placing said framework in a mold 13 containing a pulverulent material 16 wherein the framework is embedded by part of its thickness, in molding an insulating synthetic material 4 in the empty part of the mold so as to embed the visible parts of the framework 1, in placing above the mold a form sheet 2 so that the insulating material shall make contact with it and adhere to it during hardening, and after this hardening, in extracting the pulverulent material and in ejecting the obtained panel. The panel so manufactured can be provided after ejection with a second form sheet opposite the first.

A pre-fabricated hollow panel, comprising: (a) a three dimensional framework including a plurality of thrust bars arrayed in two generally parallel form planes with link bars connecting and fastened to said thrust bars; (b) a molded insulating material plate surrounding said thrust bars of one of said form planes, said plate having a substantially uniform thickness less than said framework thickness for providing a free space adjacent said other one of said form planes; (c) a form sheet adhered to said thrust bars of said one form plane in cooperation with said plate; (d) said plate having an inside free surface; and, (e) a plurality of aggregate particles substantially embedded in said free surface for providing a granular texture thereto.
