Does anyone have any experience with ICFs (insulated concrete forms)? The forms consist of 2 inches of polystyrene on both sides of a concrete wall. I am building a new house, and one of the walls in my new dedicated room will be the ICF wall--I also have the option of having ICF walls for the entire room. If these walls are finished with drywall, would the 2 inches of foam behind the drywall provide any bass absorption?

Thanks!
