SPRING 2017

Insulating Concrete Forms, or ICFs for short, combine two well-established building products;
reinforced concrete for strength and durability, and expanded polystyrene (EPS) insulation for
energy efficiency. ICF walls are made of two layers of rigid insulation held together with ties to
form ICF form units with a cavity in the center. The ICF form units are stacked in the shape
of the wall, reinforcing steel is added into the form cavity and then concrete is placed into the
form. The result is a reinforced concrete wall with a layer of insulation on each side. What makes
ICFs different than traditional concrete construction is that the forms remain in place after the
concrete is cured to provide thermal insulation. The combination of reinforced concrete and
insulation provides an ideal load-bearing wall, thermal envelope, fire barrier and sound barrier.
In addition to ICF walls there are also ICF floor and roof systems. The concept is similar in
that the ICF form is made with rigid insulation to function as a one-sided form at the bottom
surface. The forms are installed to span between concrete walls, reinforcing steel is placed and
then concrete is placed over the forms. The result is a reinforced concrete floor or roof with
rigid insulation on the bottom.
