air gap or not panel interior wall

[mikael1979]

Does anyone know if I should have an air gap after the vapor barrier when I am now going to install the panel indoors? The panel will be painted and aren't most paints dense today. Then you could say it becomes a double vapor barrier. ??

I assume you get an air gap "for free" if you need to set up furring strips for your panel (e.g., with single drywall?).

Regular paint is not vapor-tight.

If you have wood fiberboard in the interior wall, you don't need an air gap, since you have something to attach the panel to.

Correct me if I'm wrong...someone...

On the other hand, why do you have a vapor barrier in an interior wall? Or do you mean it’s the inside of an exterior wall?

put drywall instead and directly against the plastic. so no furring. drywall directly against the wall studs. Not something I would recommend to others. absolutely should have put furring. it would have gone twice as fast. shouldn't be so stingy. thanks /M
