I am buiding with a 9" form.  I am wondering the best way to do the door openings. I want to keep the door flush to the inside so they will open all the way, but the deepest sill I can find will not cover the foam.  How is this detail usually done?  Does anyone know of a door manufacture that can provide a 10.5" sill.  If not how is this typically done?  
Thanks,
Dave

I took care of this in my own way. I built a 4" thick frame inside an opening in the wall that is larger than the door. I then poured a concrete sill at the bottom. This enabled me to use a door for a standard wall thickness, 4 9/16", and a standard depth sill. What it created is a 5" inset in the exterior of the ICF wall about 6" wide along the sides and top of the door. I'm not sure how aesthetically pleasing most people would find the inset to be, but it works.

I can post detail dwgs if you wish.

I thought about doing it this way, but doesn't this creat a thermal break in the outside foam?

 

I used 11" blocks. The outer buck is 2 x 12, ripped to 11", so that has an R value around 11. The frame the door is mounted in I made of two 2 x 6s with 1" blue foam in between. I installed this with the 2x parallel to the wall so the R value of it is about 7, 4 for 1" of foam and 1/inch of wood. The threshold concrete comes short of the subfloor about 1" with foam in that gap. The door sill, which has a thermal break in it, spans the threshold/subfloor gap.

All in all it is a compromise in the thermal barrier of the wall, but no worse than windows and not a large portion of the wall area. As I used to tell my kids, "In life, you can't have everything!"
