Looking for more info on the insulation process of a knee wall. I was thinking of insulating the diagonals of the roof line. not what I'm unsure of is, was is the correct type of insulation faced or unfaced for that part of the knee wall?
Thank you for your time

The short answer is that if you're going to randomly add insulation to a wall, adding unfaced insulation is the best answer without more information. The kraft paper facing on insulation works as a vapor barrier and you usually want to avoid trapping moisture in a wall cavity.
If this is in unconditioned space, then definitely use unfaced. If this is in conditioned space, then post a picture of the wall (or describe the wall assembly) and tell us where you live and we can give you more specific recommendations.
