Steel Framing and ICF Construction

Building construction utilizing Insulating Concrete Forms (ICF) has a number of advantages and is being used primarily in residential construction. ICFs are hollow blocks or panels made of plastic foam that are stacked into the shape of the exterior walls of a home. Reinforcing steel is then added and the gap between the two layers of foam filled with concrete. This combination of concrete, steel, and foam creates a strong and energy-efficient structure. For more information on ICF systems and manufacturers, visit the web sites of Insulating Concrete Forms Ontario or the Insulating Concrete Form Association.

One of the advantages of ICF construction is non-combustibility. This real advantage, however, can be negated if wood members are used for the floor and roof framing. The addition of wood also takes away the healthy living advantages associated with the elimination of mold that can grow on organic material. Incorporating lightweight steel framing with ICF construction is the solution. Cold formed steel floor joists and roof framing are natural compliments to an ICF building. The manufacturers of ICF products commonly have construction details available on their web sites.
