Insulated Concrete Form (ICF) Construction is a modern method of construction that involves the use of hollow foam blocks which are stacked to form the shape of the walls of a building. These blocks are then reinforced with steel bars (rebar) and filled with concrete. The foam remains in place, providing excellent insulation and soundproofing. This type of construction is known for its energy efficiency, durability, and resistance to natural disasters like hurricanes and earthquakes.
