Right The spacer structure of these ICFs provides supports for attaching the fasteners used to attach the metal studs of the below-grade walls. Unless a self-consolidating concrete mix is used, concrete should be vibrated after pouring to remove trapped air as air pockets can lead to thermal bridging and weaken the cement (ICF Builder 2012).

Like almost any type of construction material, a great product can be improperly installed resulting in a not-so-great experience in the long run. Insulating concrete forms (ICFs) result in cast-in-place concrete walls that are sandwiched between two layers of insulation material. Installation of insulating concrete form systems is similar to masonry construction. Right Insulated concrete form (ICF) blocks are stacked like bricks, then rebar is set horizontally and vertically in the plastic spacers, then concrete is poured; the rigid foam and spacers stay in place to add support and thermal resistance to the wall. American Society for Testing Materials (ASTM) E2634-11. 12 in. Pay close attention when pouring to avoid over-pouring and bulges or blowouts. Report sumarizing a workshop to initiate a professional discussion about eventual benefits of the application of massive technologies in US buildings.
