Insulating concrete formwork (ICF) otherwise known as permanently insulated formwork (PIF) is an insulated in-situ concrete system of building that is quick to construct and offers levels of performance significantly better than that available from slower, more traditional approaches to building. âFlatâ systems (3rd generation) form even thickness concrete throughout the wall area similar to a conventional in-situ concrete wall. 2  In areas where there are high seismic or severe weather conditions, flat wall systems predominate as the system of choice.
