Cladding garage wall with OSB

Hello,

I have a question about the interior finishing of my garage.
I would like to line the inside with OSB boards, with squared timber and mineral wool of 80mm thickness underneath. The wall thickness is 24cm brick.
Is it possible to do it this way or will I have problems with condensation or something similar?

Thanks and regards, Christoph

You mean the roof? Flat roof? I wouldn't do it over a large area, because where should the moisture go then? But that's just my layman's opinion, because OSB is simply airtight.

OSB itself is never airtight; however, it can be used as a vapor retarder if joints and connections are glued/sealed. Enter your wall structure into the u-value calculator. Is the garage heated?

: The garage is not heated. To me, the OSB cladding with insulation just seems cheaper than an interior plaster. Besides, I think it looks quite nice, hence the consideration. Whether or not there is a vapor barrier, I just want to know if it works when the insulation is directly against the masonry.

Thanks and regards, Christoph

Yes, then just ask the u-value calculator
