Black Hawk Builders of Tahlequah, Oklahoma uses a modified form of ICF by placing the rigid foam board insulation (RFBI) inside the forms before pouring the concrete. It seems to me that there was a company that sold such a system, but I am unable to locate any information on them.
Do any of you Oklahomans know if Black Hawk Builders are still in business?Gene Leger (GeneL)
