Insulated concrete forms (ICFs) are pre-formed panels, planks and/or blocks made of foam insulation that are used to hold concrete in place to cure after it is poured. ICFs not only hold concrete in place during curing, but also serve as permanent insulation once in place. Insulated concrete forms provide backing for drywall on the inside of buildings and for exterior treatments such as brick, lap-siding and/or stucco. Walls incorporating ICFs typically deliver higher R-values (between R-17 and R-26) than conventional wood or metal frame construction. Additional green building benefits may include partial recycled content composition and contribution to a variety of credits in the LEED green building rating system.
