Forum Title: Exterior XPS / Polyiso Wall Question - Trim Outside Corners?
In traditional wall framing, the outside corners have OSB / ply at the corners that we nail the exterior corner trim to. What do you do when you're putting 2-4 inches of XPS or polyiso over the sheathing? Best I can figure is to put some additional ply over the XPS at the corners as a nailing block in the same plane as the furring strips I'm attaching the fiber cement siding to. Other options?
