Hi, new to this forum. Sorry if my question is common knowledge.
I am installing drywall in my unattached garage. There is Ty-Vek wrap on the outside under the siding. I may heat it occasionally in the winter when I work out there. I have insulated doors and a window.
I will get fiberglass insulation with craft paper for the ceiling. I already have fiberglass insulation for the walls, but it does not have craft paper on it.
Should I put poly sheeting on the walls as a vapor barrier?
