Contractors Can Use Traditional Building Measurements with ICF Studs when They Choose Fox Blocks

You are a sheetrock, residential wood frame, commercial steel stud or siding contractor that has been trained, and are efficient with, a continuous 1 1/2” wide attachment surface @ 16” on center. Our team at Fox Blocks agrees with this tradition and have created our ICF with the same continuous 1 1/2” wide attachment surface but increased it to 8” on center. Just think, when attaching sheet rock or siding to Fox Blocks Insulated Concrete Forms, you can use the same training you understand and have used in the past.
