   *Seems like an expensive way to go. Around here, pole barns are cheap space. Seems to me that the way you are going, you could get a better result at the same or lower cost with conventional studded walls. I don't care much for putting post in the ground. I know what they say about modern treated wood but I still think it is only appropriate for farm outbuildings.

   *2x6 nailer inside and out seems redundant. Have you considered using hangers or dadoes in the 6x6 and running your nailers flush with them on edge?Hey, does anybody know if 2x6 nailer is technically called girts when they're run that way? JonC

   Maybe I should clarify my situation. The pole barn was built by me 12 years ago and yes it was built with cheap storage in mind. Now I'm going to use this building to store kiln dried hardwood lumber in. So I need to tighten the building up to control the inside relative humidity. I have 1" hemlock siding on it now and it does not do a good job of keeping the weather out. That is why I'm going to put 3/8 cdx over the (Girts)to make the wall more weather tight, then the new hemlock board & bats over the cdx. My question was should I put a house wrap between the plywood and hemlock? Thanks again, Brian...

   *Brian,Forget the Tyvek stuff - 30# tar paper will do just fine

   I am building a pole barn using treated 6x6 posts. On the inside of the wall there will be 3/4 inch pine paneling, 6 mil plastic vapor barrier,2x6 nailers,and R-19 fiberglass insulation. On the o/s of the wall there will be 2x6 nailers, 3/8 cdx plywood,then 3/4 inch hemlock board & batten. Now the question, should I place a house wrap such as Tyvec between the plywood & hemlock or omit it? I've been told to use it and also been told not to use it because the wrap will trap moisture in the wall. The building will be heated in the winter. What is the consensus out there? Thanks, Brian...

   Brian,

   Does your pole building currently have a soffit overhang?
   If it does have an overhang, then is your roof composed of trusses that sit on a double girder that is either bolted or nailed to your 6x6 poles?

   If that is the case, have you/or are you going to block off the air space created between the 2 girders? Even if you currently have or are planning to have an enclosed ceiling in your pole barn, if you do not block off this girder space, then the air coming through your soffit vents will also go down between the girders and into the middle of your wall.

   Since you are covering the inside wall with insulation and a plastic vapor barrier, this air moisture will become trapped if you place Tyvek on the outside wall. the moisture will then begin to rot your wall structure from the inside out.

   Just a thought,
   Davo
