Insulating Concrete Forms. Rigid plastic foam forms that hold concrete in place during curing and remain in place afterwards to serve as thermal insulation for concrete walls. The ICF's are stacked up in the shape of your house, reinforcing steel is placed inside and then concrete is poured in between to create a high performance, solid structural wall. The ICF's remain in place after the concrete sets, and continue to function as thermal and acoustical insulation, an air and vapor barrier, and exterior wall sheathing. The foam blocks, or planks are lightweight and result in energy-efficient, durable construction.
Are Forms or molds that have built-in insulation for accepting reinforced concrete. The first patent application for an ICF was registered in the late 1960’s. Since then, and particularly in the last 4 years, ICFs have been fast-becoming the mainstream preferred building product worldwide for all of the right reasons. These large, hollow blocks are stacked right off of the truck and filled with reinforcing bar and concrete. The end result leaves you with a high-performing wall that is structurally sound, insulated, strapped, has a vapor barrier and is ready to accept final exterior and interior finishes.
