How to build interior walls in pole barn?

[Buckeye_Guy]

We live in west central Ohio, and I recently had a 40' X 40' pole barn built. I would like to install electrical receptacles, lighting, insulation, and walls. See pics below.

I am looking for guidance on how to build the walls. What type of insulation should I use? Extruded polystyrene? What about the walls? I suppose I could use OSB, but am concerned the insurance company would not approve. What about drywall? And should I first install vertical wood beams on 2-foot centers to accommodate the electrical outlets and walls?

I'd frame it up with studs. Put in the electric. Then frame it in with either drywall or some type of siding.

If I was in your situation I would build a stud wall to fit in between the post. You could do a 2x4 plate on bottom and top and then 2x4 studs every 2 feet in between the post. The post could act as a stud so you would only have 3 vertical 2x4 between the post. And put the stud wall flush with the front of the poles. You could then put r19 batts of fiberglass in them and cover with dywall.


You wouldn't have to use 2x6 or have them 16" on center because the walls wont be taking any load of building. And also using the 2x4 you wouldnt have to cut around any of the cross braces in your courners. Just make sure you make the 2x4 wall flush with the front of poles to give the nice finished look when your done.


Doing it this way would prob be the simplest and cheapest route in framing and insulation. And you can put outlets evey 2 ft if you wanted. Also you could run all the wire behind the studs easy and wouldnt have to use a dril.

Thanks for the info. I like the idea of building stud walls.

Would fiberglass be a wise choice? Just wondering if moisture would be a problem (hence my reason for mentioning extruded polystyrene).

And can I use regular ol' Romex for the wiring, just as you do in a home?

This is exactly what I did except I cut and stapled Tyvek house wrap in between the posts first but I see you had them put the house wrap on under the siding. Smart move. Just run your romex along the horizontal purlins. I used R19 Kraft faced insulation then painted OSB over that. What are you thinking for the ceiling? I went with White metal. Looks just like the siding but a lighter gauge material. It's called Dura Panels and you can order from Menards in any length up to 24' long. Just remember to add a couple inches for overlap and inconstant truss centerlines.

Personally it doesnt make sense to me to build a pole building THEN frame walls in between.Why not just frame the whole building?

Heres a pic from someone on this site,forget who. I'm doing the same for my shop. I got 8ft wide rolls of fiberglass from morton, hang it, run horizontal perlins just like the outside, hang vapor barrier and finish the inside however. I'm using metal just like the outside. Less framing less messing with narrow insulation,no drywall mess.This is how Morton does it and they are VERY nice inside.Surface mount all utilities.

Only problem I see is your vapor barrier on the outside?

Depends on where you are. In really cold climates, I think it's normal to have a vapor barrier on the inside. In the south, it's normal to have the vapor barrier on the exterior side of the insulation.
