Is using icfs as a below grade foundation system (for a crawl space) also insulating the floor. Then using sips for the structure a viable way to go. The home will be a large single story ranch design. I will be building in North Carolina (scotland county) not far from Rockingham and Pinehurst.

The insulating characterisitcs of ICFs below grade eliminates the insulkation requirement in the first floor diaphram!

Jim, sorry i shoud have more specific. The crawl space floor would be insulated. The wall structure would be sips.

I believe I understood it that way, so if the crawl walls are ICFs, you do not need to insulate the wood? first or main floor, insulating the rat slab is a good practice especially depending on whether you will be using a ventilated or unventilated crawl area. In this case a ventilated crawl causes other insulation issues.

There is some good information on closed (unvented) crawlspaces available at http://crawlspaces.org. This site has links to North Carolina specific information also. Bruce Cain ICF Building Systems Mt. Juliet, TN
