Insulated concrete forms or ICFs are blocks made out of Expanded Polystyrene, steel, and concrete. The steel bars in ICFs are fortified with concrete, resulting in a sturdy building block that offers excellent sound-blocking capabilities and proper home insulation.
These ICF blocks are first assembled together to form a wall. Afterward, the steel bars will be added to provide support to the blocks. Finally, concrete is added to the structure to further reinforce the blocks. After installation, these ICF structures are expected to last more than a hundred years and require little to no maintenance.
