I was reading that many people use thicker insulation on the outside all the way up to 12 inches thick in some cases.

Not sure why manufactures design these with equal thicknesses of insulation seems counter productive.

A monolithic type pour makes for a air tight build due to the ICF air tightness it increases the insulation effective value to its true rating.

The Nudura forms are well designed. They come in 18 x 96 inch assembled forms that swing shut to save on shipping space and are available with 4 to 12 inch core sizes.

The plan is too hire a 1 or two people and build the house myself / hire sub contractors when needed.
