Just curious if anyone has any opinions/experience with this wall type? Looking at it for a customer.
Any experience with a wall like this?

We had talked with a builder trying to use such a wall here in Colorado, but it seems it never took off. My engineer thought it was a bad idea. I don't think it will perform as well as a ICF or other wall where there is a better thermal break.

I agree. Get the insulation on the outside of the wall. If you get cold you wear a sweater, you don't eat one.

The goal is to take advantage of the natural durability of the concrete on the exterior while gaining the insulation value of the foam. My customer also likes the idea of having a concrete wall exposed to the interior. When the pour is complete there is no need for inside framing (similar to ICF's), or add finish to the exterior. ICF's are a great product, but finishing them on the exterior is another step that can go wrong.
More on the inside finish: You would have the option of leaving the concrete exposed, or to install drywall over surface applied batten strips. Electrical boxes are added to the forms before the pour. I spoke with a contractor from another market who has experience with this setup and he said the electrical wasn't a big deal to put in the form.
I plan to do some cost comparisons later to see what the overall price difference would be.

I foresee huge cost implications pouring 2 separate walls. What R value do you need to acheive where you are?

R-18 continuous is the minimum goal.
This would be poured all at once.

did any of you here about Superior walls they are precast concrete foundation system https://youtu.be/nNq9jdXKpD0

I've heard that wall called a 'Sandwich Wall' because the foam is sandwiched between concrete. I've seen it used in commercial and agricultural uses but not very often, maybe once or twice in the past 5 years or so.
Here, we would have to get an engineer's stamp on that.
Depending on the application, ICF may be the better route.
