I would like to supplement some existing old woolly pellet insulation in my attic using 6" thick fiberglass batts. Since the size I need seems to only come faced, should I:
- Face it up (facing the roof, opposite what it would be if I were installing it from the room below on its ceiling) and be able to staple it to joists, or
- Face it down and not staple it, or
- Peel the paper off?
