Hello,

I’m in the process of updating my garage. And currently the walls are bare (this is a detached garage) my goal is to make this into a gym area.

My question is, is Insulation required? And is it okay to just add dry wall without insulation?

And the part that is confusing me is ”IF” i do add insulation i dont know if a vapor barrier is required. As im finding conflicting information.

I live in North West Indiana so the temps vary from cold to hot.

Unsure if there is insualtion that already has a vapor barrier, or covering with plastic still Necessary?

Sorry for all the qestuons as im new to this type of thing.

Thank you,
