Window Sill/Jamb Wall Design Feedback/possible issues – GreenBuildingAdvisor

GBA advisors,

Hello all, looking for feedback on the attached design Climate zone “5A” , Connecticut Building Codes.

Attempting to follow “Joseph Lstiburek’ perfect wall design as well as info gathered from the GBA site.

https://buildingscience.com/documents/insights/bsi-001-the-perfect-wall

(Open Joint Vertical Cladding with rain screen, 4″ External Rigid foam insulation, no cavity insulation, 2×4 construction, European aluminum windows).

Main concern is moisture control within the foam and internal OSB sheathing.  Thinking of having a gap (silicon dimples between internal OSB and first layer of ridged foam to allow wood to breath).

Thanks in Advance
