What Are Insulated Concrete Forms?
Insulated Concrete Forms (ICFs) are blocks or panels of concrete, usually reinforced with rebar.
They can consist of cement, polystyrene foam, polyurethane or sometimes cement bonded wood
fiber. One reason ICFs are considered "Green" is that they often use a mixture of recycled wood and
cement.
They are also very strong and can resist strong winds. ICFs are very popular in areas that are
susceptible to hurricanes, and builders and residents in the midwest have taken note of the ability of
structures built with Insulated Concrete Forms to withstand Tornado strength winds. In fact, ICFs
have become popular to use in construction of "tornado safe structures" for people who live in these
areas.
