Abstract: An insulated concrete wall having a centrally disposed layer of insulation and utilizing a unitary means for simultaneously maintaining form panels in a predetermined spaced relationship, and for maintaining the insulation in a predetermined spaced relationship between the form panels such that a permanent and reinforced mechanical connection is provided between said concrete walls and said interposed insulation.

Abstract: A method for installing insulation on cast-in-place concrete walls. The method makes efficient use of expensive wall ties used during cast-in-place construction and provides for a quick, easy to learn, cost and labor saving method for insulating concrete walls. Furring strips are firmly and permanently affixed to cement walls by slotting the furring, placing them over the wall ties and driving a wedge-like member through the aperture of each wall tie which extends past the furring so that the furring is pressed tightly against the wall. Insulation panels are then affixed to the furring. The method may be easily adapted for insulating cast-in-place concrete ceilings.
