We have this ICF house with a high energy heal trusses. The energy heel is not consistently set back from the ICF wall. We need to put EPS on the OSB, flush with the ICF for EIFS coating. Anyone know any tricks or tips for shimming that area to make that work?

I am not finding any photos? Does anyone use trusses anymore that are not energy heel? Since this is in the doors/windows section, is this about shimming doors/windows and not about shimming ICF wall and truss interface?

When we did ICF construction, we would string the top of walls to make certain they were absolutely straight and make sure all the dimensions absolutely agreed with the truss design dimensions, adjusting bracing as needed both during and at the end of the concrete wall pour to ensure this was the case. So I don't recall ever having any issues requiring shims for any of the various exterior wall finish options we used.

It shows the photos as attached. This is the best section for this thread because it is EXTERIOR FINISH related. The walls are poured, the trusses are on, let's just try to help the customer move forward.

Ok, whatever you did, I can now see three photos. The images are blurry, but that is likely because of the small file size allowed by this forum.

As far as I can determine, the ICF walls look straight and it appears the OSB exterior sheathing surface above the ICF walls is only slightly recessed from the ICF exterior surface. What would you estimate this difference to be?

I would think an EIFS subcontractor would either make sections flush if the difference allows adding the waterproof barrier and mesh over the OSB or making the OSB section proud by placing EPS panel over OSB and using decorative EPS trim at the OSB/ICF interface. However, EIFS is really outside my subject matter expertise, so hopefully an EIFS subcontractor will provide some good advice.

It's not fun but attach the foam with cement, then use a 2'x2' piece of plywood with 60 grit sand paper glued to the surface. You'll look like a breaded cutlet when your done. It should even the surface. You can use a Sureform but they are too small to make the surface even.

For anyone else. Put the energy heel inside the walls and not on top. Much easier and stronger.
