Unfinished or uninsulated attics need a layer of protection against air migration. The facing on the insulation is a vapor barrier it needs to be placed face down. But if the floor is covered in plywood you can t stuff enough insulation beneath it to do the job sufficiently not even in warm climates. The best choices for this type of application include comforttherm kraft faced or unfaced with a separate vapor retarder film placed over the insulation.

Before installing insulation in garage walls clear the area inside your garage of any obstacles.
