Styrofoam in Construction? Here's How In this video, we explore the innovative use of Styrofoam in construction through Insulated Concrete Formwork (ICF). ICF is a building method where Styrofoam blocks or similar foam materials, like polystyrene or polyurethane, are used as molds for pouring concrete. These blocks are stacked, reinforced with rebar, and then filled with concrete to create a durable, energy-efficient structure. This technique is commonly used in residential, commercial, and even
