A system for insulating only the interior surface of a concrete wall to be poured between a pair of interior and exterior wall forms. The system includes horizontally extending elongated tie strips which connect to each of the wall forms to hold the wall forms spaced apart, a single layer of insulation positioned in contact with the interior wall form, and a plurality of connectors for securing the single layer of insulation to only the interior surface of the concrete wall. The connectors include an enlarged head portion which engages the insulation and a web portion of smaller cross section which extends through apertures in the insulation and into the space between the wall forms, the web portion including openings for the passage of concrete therethrough.

[ What is claimed is:] [1.] In a system for insulating only the interior surface of a concrete wall to be poured in between a pair of interior and exterior wall forms composed of non-insulating material, the invention comprising:(a) horizontally extending tie means for connection at opposite ends to each of the wall forms for holding the wall forms horizontally spaced-apart;(b) a single layer of insulation, said single layer of insulation being the only insulation layer for the concrete wall and being positioned in the space between the spaced-apart wall forms and being positioned only in contact with the interior wall form;(c) said single layer of insulation having a plurality of apertures;(d) a plurality of connectors, each of said connectors having an enlarged head portion and a web portion of smaller cross-section than said head portion;(e) each of said web portions having a plurality of openings for the passage of concrete therethrough, and said web portions being of a cross-sectional size for passing through said apertures and into the space between the wall forms; and(f) said head portions engaging said insulation surrounding said apertures for holding said single layer of insulation in place while the concrete is poured into the space between the forms and flows through said plurality openings in each of said web portions for securing said single layer of insulation to only the interior surface of the concrete wall.
