Won’t double-stud walls have a condensation problem?
Using exterior rigid foam solves thermal bridging and prevents condensation within the batts in the wall cavity. Double-wall construction also solves thermal bridging, but what about the dew point within the batts? Won’t there be a condensation problem?
I’m designing a new house and need to choose a wall assembly: double-wall with batts or loose fill vs. single-wall w/ exterior rigid foam.
