Building Blocks - The ICF block

This is a Polysteel ICF block. It has 2.5" of insulation on each side with fit together channels on the sides. They have a metal grid molded into them every 6" that work like metal studs. You can fasten any exterior or interior directly onto the blocks with screws. There are strips of sheet metal welded to each grid that act like metal studs. These blocks have a 6" center that gets filled with concrete. This means you end up with 11" walls before the drywall or brick are installed. You can order them in 4", 8" and 10" also. The contractor told us they poured 36 yards of concrete in the 1st story walls on Monday.
