old attic insulation question
Hi,
My attic has 2x6 joists. The (ancient) fiberglass insulation between the joists appears to be matted down to about 2" thick.
Do I rip it out and replace with 6" thick batts and add more above that?
Or do I leave it, add 4" batts, and add more above that?
All opinions appreciated.
Regards,
Theodore.
