My house entire attic has plywood flooring over the joists/insulation.
It is nailed in and a pain in the ass to remove.
What is the best way to add additional insulation to the attic? I worry the plywood/insulation underneath has a bad r value.
Do I need to take up all the plywood and re insulate the batts? Should I just loose fill on top of the plywood?
Ideally I want to air seal it to but taking the plywood up will be a nightmare.
