Now that I some outlets in, and some wire strung I finally got the lower portion of the walls and insulation up.

The thing I am wondering now is …. should I have a vapor barrier up?

I read a bunch, but can’t find a real answer.

I want to make sure that no water comes in through the seams of the back door.
So I tried to fill all the gaps with sealing foam, then that super sticky red tape.
Then I put vapor barrier over the entire back wall.

There were a lot of holes in that back wall.

Those strips you see are cement board.  The center section (doorway) needed to be built up a half inch, otherwise the back wall would have been bowed in the center.
And I did not want to use wood.
