Replacing Fiberglass with Mineral Wool
Gable and roof vented Cape cod attic.Zone 4 SW MO
I believe it’s r19 between the ceiling joists with unfaced r30 rolled across it.
I want to replace the r19 with r30 roxul. The r30 fiberglass will go back over it.
Should I leave the Kraft facing in place and just pull the fiberglass from it or cut the facing out?
