BTC_P2P -- 177d That has to do with improper building techniques not the sheathing / wrap outcomes. But installed / flashed correctly zip will last centuries, and osb just can’t. Mostly because of the house wrap. The issue with sheathing covered in a house wrap is that the wrap has air bubbles behind it (even with the most meticulous install) and the temp differences between the conditioned space and the outside environment create a dew point. The dew can’t move through the house wrap so it all stays trapped behind it in the interior walls of the house, molding and degrading them. Zip solves this problem. reply [1 reply]That has to do with improper building techniques not the sheathing / wrap outcomes.

Unsolicited advice: if you’re building a house or any conditioned structure - use zip sheathing. OSB sheathing +house wrap is not a good engineering solution.
Depends...
On what in your opinion?
If you don't flash them correctly, both will fail at some point

Kinda disagree with that statement. I have seen them both fail in the field lol
If you truly want a building to last for centuries you build out of mansory, steel, concrete and/or rammed earth or a combo of all of them. That will last forever lol
