You can use standard R19 fiberglass and staple to joist faceOK, now that you guys have helped me out with the ceiling (drywall instead of a drop ceiling) I'm curious what insulation I should use.
I have what I would call a solid I-shaped joist in my basement ceiling where the distance from the top of the ceiling/bottom of the floor boards to the very bottom of the joist is about 9.5" and the width is around 15".
Any suggestions on type of insulation or mounting technique? Paper backed versus just rolled? Batts versus roll? Stapled versus those little hangers that go from joist to joist?
