What is Insulated Concrete Formwork (ICF)?

ICF is a system of formwork for reinforced concrete that stays in place as a permanent interior and exterior surface for walls.

ICF forms are modular units that are stacked and filled with concrete. The forms lock together somewhat like Lego bricks and serve to create a form for the structural walls of a building.

ICF construction has become commonplace for both low rise commercial and high performance residential construction as more stringent energy efficiency building codes are adopted.

  • The ICF blocks are stacked together like Lego bricks
  • The entire structure of the house is built with the ICF, and the core is filled with concrete.
  • The end result is a building that is incredibly energy efficient, strong, and comfortable to live in.
