Insulating Concrete Forms (ICFs) represent one of the fastest-growing sectors in the construction industry today.
ICFs are hollow blocks or panels made of Expanded Polystyrene (EPS) that a construction crew stacks to create the exterior walls of a residential or commercial building.
Workers then add reinforcing steel and fill the gap (typically 4” to 8”) between the two layers of foam with concrete.
This combination of concrete, steel and foam creates a very strong and energy-efficient structure. After the concrete has hardened, the forms stay in place and become the insulation for the walls.
