Corrugated siding… will the nails into the sheathing cause condensation issues? – GreenBuildingAdvisor

We have 2×8 walls with r30 rockwool and an Intello vapor smart membrane installed. On exterior the sheathing is LP Weather logic (no exterior insulation). We have coravent for our rainscreen and are getting ready to have corrugated siding put on over that. Between the two, there should be plenty of airflow behind the siding but I’m wondering about the screws penetrating into the sheathing and whether they will cause condensation issues in the walls? It sounds like it would be impossible to only screw into the studs so there would be many places where they go into the sheathing only. We are planning to use the shortest screws possible, but not sure if there are other solutions?
