Detailing an Attached Garage

lynn777 | Posted in Green Building Techniques on

I am planning on finishing my attached garage. When we moved here, it was partially finished (ceiling, walls facing interior of home). I plan on finishing the walls that are not attached to the house facing exterior. Do I need a vapor barrier (plastic)? Do I use faces or unfaced insulation?

Thank You So Much,
Lynn

    Whether or not you need a vapor control layer between unconditioned (assumption) and conditioned space depends on your climate zone (location).

    What you *absolutely* need between your garage and living space is a well detailed air barrier that prevents air contaminated with exhaust fumes, etc. from migrating to the inside of your home.

      Thank you for your reply. I live in Wisconsin.

    To what extent will the garage be conditioned? If none, then don't add any insulation to garage exterior walls.

      I plan on installing a heat and AC unit eventually.

        Then the ext garage wall design should be the same as a house wall in your climate. Lots has been written about that so no need to repeat it.
