Wall Intersections – Thermal Break? – GreenBuildingAdvisor

2001 gut reno – CZ 3A/4A

Can someone please help me figure out what to tell my contractor to do for interior wall intersections like the ones in the attached photos? We are doing Rockwool in the stud bays, but I’m at a loss for what to do in these areas.

Would not insulating create a thermal break here and lead to potential issues? Or is it ok to just re-caulk / foam the seams and call it a day (like it was previously done when the home was built)?

Or do we need bother insulating/sealing those corner seams at all?

For extra context, here’s our assembly:

Hardie, Benjamin Obdyke Slicker Max rain screen, Tyvek commercial wrap, OSB w/ taped seams using Siga Wigluv (Fentrim at slab)… Rockwool and drywall to come soon

Our goal was to make the home more air tight, not perfectly air tight.
