Hobbs vertical ICF-
Andrew Hobbs, owner, manufactors Hobbs ICF here in Iowa and has been a great help so far on this project. They are a highly engineered system and you can use 40% less concrete then typical horizontal forms. The vertical form appears to be superior in strength and ease of assembly. Hobbs ICF also features a higher r value of r-30, plus a very high amount of recycled content.
