As sustainable building has become the preferred (or, occasionally, required) construction method throughout North America, design professionals are turning to insulating concrete forms (ICFs). When comprising the building envelope, these materials provide occupants with a safe, clean, healthy, and comfortable environment in which to live and work. Whether residential multi-family, commercial new construction, school, theatre, healthcare, or retail, ICF structures also help reduce a building’s carbon footprint—their insulation can mean less energy to heat and cool than is needed in structures built with conventional materials.
