my whole house is framed using ICF blocks, good for 200 mph winds, heck of a good insulator, and got a discount for being fire proof, i live 20 miles from the gulf of mexico....![]()
There are many ICF systems out there. There are not big differences between them when it comes to construction and performance. Some systems break down and can be shipped more efficiently, which saves some money.
Generally ICF's are more expensive than wood framing especially if you contract the work out. On a DIY scale of 1 to 10, they are probably a 9.
They do offer significant benefits in strength, energy efficiency and sound deadening.
Personally, I think they are tough to beat but I'm in the business. We are planning a modern home utilizing ICF's for walls, floors and roofs.

Hey man, is it you that I was thinking about that posted up in the newbie section about these ?
