Exterior rigid foam, traditional stucco
For a building enclosure, would the following stack work?:
– 2×6 walls filled with blown in cellulose
– OSB sheathing
– Tyvek housewrap
– 1″ rigid foam
– 3 course stucco
– Should there be anything between the rigid foam and stucco (besides the wire mesh)? I want to be sure to establish this with the stucco contractor, and at this point he feels we can do three course stucco right on the rigid foam.
– What type of rigid foam is best suited for this (XPS, Polyiso)?
– Is this risky, or will this enclosure have adequate moisture control (assuming proper flashing/detail)?
I’m in Virginia.
Also, just wanted to give a thumbs up on the GBA subscription, the drawings and information are well worth it.
