Abstract: A prefabricated facing panel for affixation to building framework having load-bearing columns is disclosed which panel is formed from a frame of structural steel members, usually a truss, an interconnection device and a plurality of facing members such as facing stone generally marble, granite, limestone or travertine. The prefabricated panel is dimensioned to extend between adjacent columns of said building framework. The facing members have blind holes in the back thereof being in alignment with the apertures of interconnector device providing a highly wind resistant mounting. The weight of said facing members is transmitted through the frame to the columns of the building framework.
