I was informed by a colleague of mine about your show on ICF's. I was particularly interested in your method of using a ledgers to mount joist hangers. At SEMCO we have developed a hanger system for ICF's that greatly simplifies this task. The product is nationally marketed and recognized by the Insulated Concrete Form Association. If you would be interested in more information, please furnish me with someone to contact at PParkerson@semetals.com or call me at (800) 874-0335 ext.562.
