Disclosed is a tie for securing insulation to a cast concrete wall comprisin g: a head; a shaft attached to the head and having a longitudinal axis, the shaft comprising a series of barbs positioned at pre-determined longitudinal positions along the longitudinal axis, each successive barb being rotated about the longitudinal axis by a predetermined rotational increment from the immediate ly preceding barb; and, a tip on the shaft. There is also disclosed a system fo r constructing an insulated concrete wall comprising: a set of concrete forms comprising two opposing partitions set apart a pre-determined distance; a sheet of insulation secured between the partitions adjacent one of the partitions; an d, at least one tie consisting essentially of a head, a shaft attached to the head and a pointed or wedge-shaped tip on the shaft, the tie being inserted through the sheet of insulation such that the tip elastically deforms the insulation to permit passage of the shaft through the insulation and a portion of the shaft extends beyond t he insulation into a cavity defined within the forms for securing the insulatio n to the concrete once the concrete has been poured and cured. A method of constructi ng an insulated cast concrete wall and a process for making an insulation tie a re also disclosed. Inserting thetie into the insulation can be done on-site without any prior preparation of the insulation and can be inserted in any desired pattern greatly facilitating the construction of custom cast concrete walls. Insulation of both sides of the concrete wall can be conveniently done without significant additional labor. A veneer may be applied to one or both insulated surfaces of the cast concrete wall by fastening the veneer to the tie.
