I see now, it’s a pole barn with horizontal girts and diagonal strapping for shear. I’d use fibreglass blankets insulation. R16 is about 1.30sq’ of wall space.

The diagonals sheer strap is not necessary on a small pole barn with wood or steel siding. My bros chicken barn is 100x200, shear comes metal from siding only.
You can remove the sheer straps or simply insulate around them.
I’d ditch the track door, they are impossible to keep sealed. A standard res roll ups would be better, you can get them for well under $1000 each. Watch kijiji, sometimes $100.
Going insulated garage doors.
The track doors are coming off to replace steel shell and I want to heat part of it so the track doors are going.
Just did a budget for what I was planning (and with inputs here). A little too much $. Need to trim down my wish list a little.
