Hello!
Building an insulated shed and planning to use horizontal rough boards for the interior walls.
Do I need to put up chipboard first, or can I attach the boards directly?
I'm planning to have a small gap between each board (for appearance).
Is there a disadvantage for insulation by not using chipboard, as it won't be as tight?
So, it will be exterior paneling, air gap, wind barrier, insulation, plastic foil, and then... chipboard or boards directly.
Any tips or opinions?

The density should be provided by the plastic, so I don't see any insulation advantage with the chipboard. Aesthetically, however, I think I would prefer a black-stained chipboard or similar as a base for it to look better if that's relevant in this case.
Yes, it can be annoying to glimpse plastic in the gaps between the boards.
If you put chipboard underneath for this reason, you get some interesting options to consider:
Dark chipboard + dark boards or light chipboard + dark boards or dark chipboard + light boards or light + light, or blue + red or pink + pistachio or ...
You can simply choose colors based on how you want the wall to be perceived..
If it's tongue-and-groove wood and you just expect the tongue not to go all the way to the bottom, then the chipboard probably doesn't matter much. The combination of chipboard + boards probably carries a bit more load than the boards alone, but I guess the difference isn't very large. If you know you're going to screw something really heavy somewhere, it's better to add blocking there.
edit: instead of dark-colored chipboard behind, maybe wind barrier paper will suffice just as well, and it's cheaper.
