Take the 2-minute tour ×  My garage is a pole building type with
pressed wood walls and exterior siding. I want to put sheathing
on the walls for some insulation. The girts that the exterior
wall is attached to are 1.5" x 4" being attached flat and run
the length of the garage and are attached to the poles. Should I
install the sheathing between the studs letting the studs
exposed? Or should I attach the sheathing to the studs letting
the air space between the sheathing and the exterior wall?

what you're describing, but covering studs is always better than
placing insulation in between when doing so is practical. Studs
do not provide good insulation and turn into a heat sink. The
dead air space left also provides a bit more insulation. Even
better would be to insulate that space, then put more insulating
sheathing over that and the studs.  share|improve this answer
