Back to my new garage/shop

we had a great discution about the under the floor chase.
Now what about VAPOR BARRIER ON THE INSIDE WALLS.? It will be a pole type building wrapped in tyvec, With batt insulation. Was going to use foam – a little to pricy .. With a vapor barrier. And metal on the walls …..
Cellulose on the ceiling with a vapor barrier on it. Metal ceiling.
WHAT DO YOU GUYS THINK. IS there a better way..?

Vapor barrier keeps the moisture from entering your insulation. I would always us it.

Vapor barrier on both sides could trap moisture inside the wall cavity. Any external leak or even condensation could build up, rotting wooden structures and rusting steel.

Vapor barrier always goes on the inside of the wall between the insulation and the drywall (or whatever you choose to skin the walls with).

I’m with slmndr, in your climate I’d go with vapor barrier, and it’d be on the inside. It requires a bit more care in putting up the sheetrock, but I think it pays off.

I live in a far more forgiving climate than yours, so I just went with faced insulation rather than a full-on vapor barrier for my shop.

Vapor barrier always inside and makes sure you tape seams of the plastic with barrier tape.
