Exteror wall construction / insulation — new construction
Hi, I live in Zone 5a Northern IL and am building a new home.
I have questions on exterior wall insulation/construction.
I’m confused on interior vs. exterior drying/condensation/dew point and insulation.
My architect suggests the following standard construction method. 2×4 studs 16″ On center
Masonry |House wrap Tyvek| OSB| wood studs with fiberglass batts in between the studs |drywall
Is there a better construction method?
Will the studs act as thermal bridges? Should I be worried about this? What would be best insulation method outside vs inside?? In regards to drying/condensation??
I mentioned to the architect about rigid foam insulation on the outside but he said something about not liking it because it did not provide any structural support. How is this addressed?
What would be the optimum construction method? Something like this?
Masonry | Air Gap | Tyvek | Rigid Foam |wood studs with spray foam in between | drywall ??
