While there are a number of ICFs on the market today, our experience has been working with Eco-Block ICFs, and these
are the ones being discussed in this section.
ICF stands for Insulated Concrete Forms, and it is the construction method for the new millenium. They are modular blocks
made of expanded polystyrene, which, once put in place, create the form into which concrete is poured.
Concrete with reinforcement is placed between the forms to provide a high strength monolithic concrete wall having excellent
fire resistance and high resistance to sound transmission. After the concrete has cured, the ICF stays in place and becomes
the insulation (interior and Exterior) for the walls of the home.
No additional vapor and air infiltration barrier is required. The completed wall has a fire resistance rating of
3 hours (6" thick concrete) or longer and provides a sound transmission class (STC) of 50 or better.
Below, you will find additional links that will give you more information about ICF construction.
