What are Insulating Concrete Forms?
Insulating Concrete Forms (ICF) are hollow blocks or panels made of EPS (expanded polystyrene) plastic foam that construction crews stack into the shape of 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, which cures and hardens into a monolithic core. The foam panel stays in place. This combination of concrete, steel and foam creates an incredibly strong and energy-efficient structure.
Not even a category 5 hurricane can take out an ICF built home!
