Wall insulation – GreenBuildingAdvisor

I’m building a house zone 6 and care a lot about air quality. I think current code requires enough R value that I’m not as concerned about energy efficiency.

Talking with my builder – he recommend the following double stud wall assembly:

siding, tyvec rain screen, blue wrap, sheathing (plywood), rockwool, intello. Then another wall for electrical +/- more insulation if needed.

Would it be better to add insulation to outside? My only concern with this is condensation. With blue wrap and intello should be vapor open enough to dry? If we put a polypropylene rain screen over the blue wrap does that defeat the purpose?

If cost was not an issue I would do rockwool boards on the outside with furring but it’s getting expensive…

there is hardy wrap with polystyrene attached as another option I suppose.

thank you!
