Tyvek inside

[cutthroatxxx]

Ok so I know tyvek can lock moisture in if used inside & cause mold etc.Well in my shop there is metal behind that felt then osb &on the inside there is the thick foam board the foam is held in place by 1xs screwed into the osb.Is it safe to hang the tyvek on the inside to those 1xs as there will be room behind for air to flow behind it.Long story of why I want to do this but does anyone see a issue with it?Thanks

What are you trying to accomplish?
Tyvek will stop wet water (moisture) but not vapor.
It is printed right on the stuff.
"moisture proof , vapor permeable."
That means water vapor will go through it, but water will not.
