I am dividing up my 30 X 50 polebarn into a shop / storage side and a "man-cave" side. I have the outside walls studded and insulated with R-13. I'm planning on a drop ceiling for the man-cave side, but I want to add insulation above that.
I have attached a pic of what the roof looks like now. Can I just put some 1X2 blocking up between the trusses and put the R-30 insulation on top of that, or is the drop ceiling strong enough to just roll the insulation on top of it?
If you install the drop ceiling with sufficient hanger wires, you should be able to just roll the fiberglass insulation out on top of the suspended ceiling. Just be sure that whatever light fixtures you install are rated IC.
