Electrical

1. Special electrical boxes are available for ICF blocks that mount securely in the foam.

2. Boxes may also be mounted into the concrete wall itself by removing foam.

3. The preferred code compliant method is to install electrical into the EPS foam on the face of the wall.

a. Cut chases at least 2” to 2½” deep so the finished wire or conduit is ¾” minimum from the wall face to avoid sheetrock screws hitting any lines.

b. Check local code requirements when planning your project.
