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.
So you have batt between the joists insulating the ceiling then plywood on top Seems fine, though unorthodox Are you having issues Just seal the plywood then if you don’t use the attic space for storage or anything put your insulation of choice on top Just make sure to extend your attic access upward Is the attic space vented, with on the ends, roof line, or another way
