4 inch rigid foam w/ LP Smartside board and batten concern – GreenBuildingAdvisor

Morning, new to the forum here! I tried to post an attachment but had some issues. 

Question regarding how our contractor executed our additional rigid foam insulation. I have concerns with the LP Smartside board and batten warranty as well as longevity of foam with the layering due to water/pests. Description of wall from inside to outside below. If anyone has insight on how to post larger photos/files, I could supply those.

1/2” gypsum board 

2×6” studs 24” or 20”  o.c., dried cellulose between. 

9/16” OSB

2 layers of EPS r 15.2 

2×3 nailers/furrings running horizontal at 24” oc, 6 inch nails into every stud 

block-it housewrap

LP Smartside Board and Batten 

Any help is greatly appreciated.
