Hi,
here are some examples of what I am talking about. I think there are
about a dozen or so different manufacturers, each with their own
design. Basically you put up the foam and the rebar and pour the
concrete inside the foam.

Actually, there are about 50 manufacturers of ICFs. My company does work
for five of them

www.standardicf.com
www.integraspec.com
www.reddiform.com
www.greenblock.com

But, they are not foam walls. They are concrete wall, with foam lining both
the interior and exterior to provide superior insulation, good sound
proofing, and huge energy savings. Not to mention hurricane and tornado
resistance. If I was building a house today, that is what I'd use and save
40% or more on heating bills.
