Sliding door insulation?

[wantacoe]

I made a 9x9 sliding door in my pole building. It is built out of 2x4's with 7/16 osb sheets. It is an interior door that divides the unheated and heated part of the building. I am using unfaced fiberglass insulation. I have already hung the door and put the sheeting on the heated side of the door. Do I need a vapor barrier and if so how would I do it with the sheeting already on? Thanks for any help.

In a pole barn, I really wouldn't sweat the vapor barrier in an interior sliding door.
