A new prefabricated wall panel is the basic unit of a new, more efficient and stronger wall system. The wall panel is manufactured from a plurality of foam sections sized to leave vertical and horizontal voids into which concrete is later poured, each foam section having an inner and outer surface and two sides; and a plurality of fastening strips. The fastening strips are longitudinal metal strips being situated between the sides of two foam sections. Each fastening strip has two longitudinal fastening strips projecting perpendicularly to the longitudinal fastening strip and the fastening strips being adjacent to the outer surface of the two foam sections. The fastening strip also has a plurality of clearance holes in the longitudinal fastening strip, a plurality of embed tabs projecting from the edge opposite the fastening strips, each embed tab having at least one hole, and between each pair of embed tabs, a foam tab to hold the two inner sides of the foam sections in place and partially separate the foam sections from the concrete to be poured into a form.

A buck panel adapted to be interconnected with other panels to form a buck to frame a bulkhead or an opening in an insulated concrete form wall for receiving a window or door. The buck panel has a foam portion, a central support beam, a first lateral support beam, and a second lateral support beam. The central support beam is positioned longitudinally within a center portion of the foam portion. A plurality of wings extend from the central support beam in such a way that the wings protrude from an internal surface of the foam portion so as to be received in concrete poured over the internal surface. The first and second lateral support beams are positioned longitudinally within a first side and a second side of the foam portion, respectively.
