Commercial Girt Question

[JF1]

I'll try not to make this confusing.

I am planning on building a 32x32 pole building. I like the idea of using commercial girts horizontally between my posts so I can frame inside and out at same time, and it wil make insulation a breeze. Plan is to us vinyl siding on the outside when all is done. 6x6's on corners, 4x6's in line.

What size girts will be easiest to use? I was thinking 2x8's so my osb will be flush from my treated skirt board to the top above my truss plate. I just watn to make sure my math is correct. 2x8 is 7.5", 4x6 is 6", 2x10 treated skirt is 1.5". Sooo, if I'm right, I can flush my 2x8 to the inside of my post, and it should line up with my skirt board.....or am I missing somethin?

I too was considering doing the flush frame design, and frow what I have seen, you use 6X6 post at all points or 3 (2X6) laminated together (turned so the 5.5" side faces the other posts). I haven't seen any that used smaller post in the wall.?. Also, the skirt board is cut to fit between the posts, not on the outside. And the trusses all set ON each post, so there aren't "trussplates". Then, you just use 2X6 girts, flush on the inside and out. Hence the name flush frame.?. Everything is flush with BOTH inside and outside of each post. Anyway that was my interpertation of this style of building. Check this thread.

Mine are built the same. The only difference is my posts extend through the trusses which are attached to both sides of the posts.

I am trying to avoid only setting the trusses on the posts and wanted them to be set 2'OC. Obviously, placing my posts 2'OC wouldn't be cost affective. My thoughts were if I use 2x8's them they would stick out the same distance from the posts that my trussplate and skirtboard would.

Why would you want all those extra trusses in the way? Trusses set at 12' work better and take lot's less labor. You also end up with more storage space.

By putting the skirt board and truss plates on the outside of the posts, I believe you are negating the purpose of a flush frame building. Instead of 2X8, might as well just do a regular pole barn with 2X4s on both inside and outside of the posts. If you are wanting to insulate, do like Morton does and drop a blanket down between the posts. Are you wanting the truss spaced 2' because of composition roofing, or what? You seem to be doing what I was trying to do, pole barn, flush frame, insulate, and I want 8/12 pitch comp. roof to match my house. I finally came to the conclusion, the added work, lumber to be able to set trusses at that spacing, it will be just as easy to stick build. Plus my O/H doors will be on the eve side, no way to have poles where they should be, so I would need some massive headers, etc.......so I have started looking to just do a stick frame. I really like the idea of a flush frame, but I don't think is is the best option for me.
