INSULATED CONCRETE WALL SYSTEMS
INSULATED CONCRETE FORMS (ICF)
ICFs can consist of hollow foam blocks that are stacked one atop another, or foam planks or panels that are held together with plastic ties. They can be used to form various structural configurations, such as a standard wall, post-and-beam or grid.


CONCRETE MASONRY UNITS (CMU)
CMU walls are built with hollow 8”x8”x16” hollow-core concrete blocks. They’re very popular in the South. Foam insulation can be applied to one or both faces of the completed wall.


INTERIOR INSULATED CONCRETE
This is a forming system that uses non-conductive ties to hold the insulation at the center of the inner and outer forms. Manufacturers point out that the placement of the insulation protects it from damage. Photo: www.thermomass.com


SHOTCRETE SANDWICH
Rather than using removable forms, shotcrete panels are built by erecting a foam core with steel reinforcement. A pneumatically applied fiber-reinforced concrete called shotcrete is then blown onto the panels, and the surface troweled smooth. The manufacturer claims that this results in a stronger wall than concrete. Photo: www.solarcrete.com
