b) one or more retaining tracks secured to a floor slab or footing and sized to retain a bottom end of one or more of the prefabricated panels; and
c) one or more concrete columns disposed within the longitudinal channel in the prefabricated panels wherein the embed tab is embedded within the concrete column and at least the second flange and the adjacent internal surfaces of foam material are in physical contact with the concrete column.
4 . The insulated wall system of claim 3 further including additional foam disposed between the internal surfaces of the foam material to form a longitudinal channel that is centered around the embed tab of the fastening strip.
4 . The insulated wall system of claim 4 further including additional foam disposed between the internal surfaces of the foam material to form a horizontal channel located at the top end of the foam material and a horizontal channel located at the bottom of the foam materials, both the top channel and bottom channel being in fluid communication with the longitudinal channel, wherein a upper concrete beam is disposed within the top channel and a lower concrete beam is disposed within the bottom channel.
6 . The insulated wall system of claim 5 wherein the concrete column, upper concrete beam and lower concrete beam are formed in situ by pouring a concrete slurry into the longitudinal channel, upper channel and lower channel.
7 . The insulated wall system of claim 1 wherein the second flange is comprised of two or more a flat panels disposed perpendicularly to the connecting flange in a series along the longitudinal axis of the connecting flange with the embed tab being disposed between the two flat panels.
