I have ripped up the carpet in the master bedroom and found that between the sheets of plywood there is cold air blowing in because part of the floor is over the garage.
I want to pull up the nailed down sheets of plywood to add insulation and then I guess I want to screw it down.
What tools do I need to make pulling up the plywood easy? What screws should I use to secure it back after adding insulation?
(The 2nd question is more geared to another one I am about to post on how to remove the squeaks from a wooden floor)
