Insulating concrete forms result in cast-in-place concrete walls that are sandwiched between two layers of insulation material. These systems are strong and energy efficient.Traditional finishes are applied to interior and exterior faces, so the buildings look similar to typical construction, although the walls are usually thicker.

A major appeal of ICFs is the potential for reducing energy to heat and cool the building. Some estimates place the savings at 20% or more. The air tightness of ICF walls are 10-30% better than frame-with compatible windows, doors and roof. As a result, assuming a 100-year service life, one single-family ICF home has the potential to save 110 tons of CO2 compared to a traditional wood frame home.
