I am trying to figure out the best way to insulate my pole building (I guess not technically a pole building, it's framed). It is 24'X48', 6" concrete floor, 9' ceiling, 4/12 pitch metal roof. Trusses are spaced 4' OC, and wall studs are 2X4, 2' OC spacing. 1x6 (oak) board and batton siding.
I want to section off the rear portion of the barn, so I'll have approximatley 20'X24 framed in.
The question is: What's the best way to insulate this? I am thinking R-13 fiberglass encapsulated in plastic (I can't remember what this stuff is called) for the walls. The ceiling is my big concern: the metal roof will drip on the inside as it is; when I heat this space, it will be a rain forest.
Should I slip 1.25" thick beadboard between purlins so it's against the metal on the underside of the roof, and then insulate the ceiling with fiberglass as nomal, or is there a better way to do this that will prevent condensation from dripping off the metal?
I want to do this right the forst time...
