Interior wall purlins

[not sure]

Post frame garage. Heres my plan. I've put fiberglass insulation between the poles. I'm using vapor barrier, then interior purlins and ribbed steel. Vapor barrier first then purlins? Or purlins then vapor barrier?

My next question is about the purlins, which ever wall i do first the boards get attached to the corner poles. Then when doing the opposing walls if you run the purlins at the same height they interfere I the corners. So should i go above or below the other purlins?

Thanks for any help i have 0 building knowledge (mechanic by trade) and sorry if my terminology or questions are confusing. I'm confused myself

I did the horizontal purlins (sp?) first, then plastic.

The building already had one at the top for a support, so it was easier to just hang the plastic on it and have it hang straight down. Also, I didn't want anything touching the insulation if I could help it.

Look at the pics in my build in the sig, pg. 2, I think shows it.

Those are sheeting girts, purlins are in the roof.

At the corners, if you put the "purlins" on the side wall above or below the ones on the first wall you did, the screws that hold the metal on will not line up. If you are ok with that then proceed that way. Otherwise have the side "purlins" meet the ones that you first put up and connect them with toe-nailing or screwing.

Yeah, girts, thats it, i couldnt remember.

I forgot to answer that part of the question.

I did one wall then butted the other into it and toe-nailed it from top and bottom.

I wanted all the screws to line up like mentioned, and all the girts to be same height around the shop.

Plastic then girts. I did the other way because I started on the girts before deciding on the vapor barrier. I wished i would have done it the other way.

You can put a nailer in the corners or drill pocket holes to attach to the face of the first girt that goes past the corner. I like the pocket hole but it can be tedious and may seem out of place in framing.

I read the title and said exactly the same thing,funny how purlins term gets misconstrued
