Looking for ICF builders I ran across a product I've never seen. Would like to know more about it if anyone has any information. It's a 10' tall x 4' wide panel consisting of fiber cement board, cement core, fiber cement board, insulation and then a third layer of fiber cement board. Fits together tongue and groove. Comes with 4" or 6" spacers for the poured concrete core. Any experience with this or have a name and manufacturer?
