dakremer your pole shed has metal roof and walls ?
You are going to be dealing with condensation when you heat the inside, this will drip.
My suggestion is leaving an air gap between the tin and the insulation.
WET fiberglass batts have NO insulating value !
One option of doing this is make wafer insulation panels (much like they use in log homes with exposed rafters ! )
Rigid styrofoam comes in 4ft sheets.
My shop in Canada I had 8ft spaced rafters on a POLE SHED.. i I used 2ft x 8ft 2” rigid styrofoam. (The same panels they use here on the putside wall of houses or concrete basements) .I used 2 layers of 2” rigid . 1 layer horizontal between 8ft space. ,2nd layer the long way to cover seams.
On the walls I suggest an insulation that has foil on one side. It attaches like a bag,and its waterproof.
Unfortunately the insulation cost more than building the walls. I limped through part of the winter with nothing (In Canada its COLD in winter, spent half the time trying to heat the building so it was warm enough to play !)
BEST of luck in your building, !

So if you see the drawings up above, there will be an air gap. the girts are actually on edge (not flat like I have shown). So there’ll be a 3.5” cold air gap between the steel and the insulation – I’m hoping that will be enough to stop condensation. We arent going to be at this house for a long time, so I’m trying to spend as little money as possible to insulation (while still doing it correctly, or course). 4×8 Foam sheets will be too expensive for what I want to spend, unless I can find some good used ones around. Iowa gets really cold in the winter too. I’m not planning on continuously heating it. Just heat it a few times a week (maybe). The heat source will mostly likely be a wood stove. Hoping to just get enough insulation in the roof to hold in some heat.
