<p>An insulated building panel includes first and second spaced apart layers of concrete (12, 14) having a layer of insulating material (16) sandwiched therebetween. Extending through the insulative layer are a plurality of connectors (20) having their opposite ends (28, 30) protruding into the two concrete layers (12, 14) and having their central portions (26) extending through the insulating material (16). A boot seal (22) is positioned on at least the first end portion (28) of the connector (20) for sealing engagement with the insulation layer (16), thereby creating a vapor barrier to prevent and inhibit migration of moisture through the insulation layer (16). The opposite ends (28, 30) of the connectors (20) each include a holding surface (38) facing at least partially toward the central insulative layer (16) and holding the concrete layers against movement away from the insulative layer (16).</p> |
