What is ICF?
Insulated Concrete Forms (ICFs) are high–density polystyrene (EPS) blocks, panels or moulds that have built-in insulation for accepting reinforced concrete. These hollow blocks are stacked and concrete is then poured into the hollow space leaving you with a high-performing wall that is structurally sound, insulated, contains a vapour barrier and is ready to accept final exterior and interior finishes.
With many advantages including ease and efficiency of the installation process in addition to the resulting strength, durability and insulated properties of the structure. Since it fits together seamlessly, air infiltration is reduced increasing the insulation performance of the building and thus lowering you energy bills.
