A lightweight structural concrete wall panel for house construction, includes a sandwich construction of two thin fiber reinforced concrete faces enclosing vertical panels of insulation material consisting of expanded polystyrene. Vertical structural concrete ribs between the insulation panels are used to interconnect the concrete faces. A continuous track system cast in the upper edge of the panel and projecting connect bars at the lower edge of the wall, connecting this wall to the surrounding structure in such a manner that the floor slab can be poured after erecting the walls. The face of the wall panel can be cast in such a manner as to appear as siding or another desirable building surface. Window and door openings can also be cast into this wall.
