Never worked with insulation before. My laundry room shares a wall with the cold room and it's always freezing. I justbwant to confirm that when i apply the vapor barrier, I would put it first before putting in the insulation. there ks no drywall on the cold room side. attaching a picture. there is currently foam board there which I will remove because it doesnt help. the insulation i am used is R-24. appreciate all directions and thoughts if something seems off

Yes remove the foam. I would glue r-10 foam board to the interior side of the walls that will back on the cold room. Seal all the seams with tuck-tape. Then frame on that side. You can the add more Roxul insulation in the framed wall.
