Fox Blocks Insulated Concrete Forms - 4" core wide straight block (12 block bundle) 64 square feet per 12 unit bundle

Insulated Concrete Forms (ICF) enable fast building construction and easy concrete pouring in poor weather conditions.  In addition, the concrete steel-reinforced wall system is robust, offering more resilience against disasters like fires, hurricanes, and earthquakes.  

Each ICF block comprises two Styrofoam Expanded Polystyrene (EPS) foam sides joined together with six robust and full-length injection molded plastic ties. The blocks are stacked tightly and interlock end to end to the desired wall length.
