Vapor barrier on the wrong side...

[Johan_Grip]

I have converted my garage into an office/hobby room. I put up a wall against the garage door with 1 meter between the door and the wall, to be used as storage for garden tools. I was a bit too quick here and missed installing a vapor barrier behind the OSB on the inside of the wall. The inside wall is completed, so it's too late to change that. Now I need to install insulation and OSB from the other side, i.e., the outside of the inner wall (facing the garage door).

The question is: Should I now install a vapor barrier on the outside of the inner wall, or should I completely skip the vapor barrier on this wall?

install vapor barrier

Do not place the vapor barrier on the wrong side

How thick insulation do you use, do you even need a vapor barrier?

How thick insulation are you using, do you even need a vapor barrier?

90 mm. I'm not really sure. It's 1 m to the wall with the garage door. The garage is poorly insulated, so we probably won't use the room much on days below 5 degrees.

Better to skip it then?

 

[Stensson11]

Rather skip it then?

Yep

Here you can read some theory about not using a vapor barrier
