Hey All,

We are considering a change to our exterior cladding.  We’d like to change the lap siding on the front wall out for a ‘thin-brick’ veneer.  

WALL COMPONENTS (see atch’d):
1. 2×6 stud 
2. OSB sheathing
3. Prosoco R-guard and Fast Flash (W-ARB)
4. Two inches of Polyiso with foil face with stainless steel screws into OSB
5. 3/4″ rain screen battens
6. Lap Siding and Trim

For the swap, I am thinking we’d replace the 3/4″ battens with a rain screen matting like “Mortairvent” (link below). Then, add the metal lath followed by mortar and synthetic brick.

I found a detail on GBA for this (see atch’d and link).

Would we need to change the screw pattern for the Polyiso to ensure fastener contact with the studs to support the thin-brick? 

The detail doesn’t show fasteners for insulation.

Thanks
WD
