Here is a photo of the 8 ft batts the way Morton does it, as mentioned in an earlier post. I put steel on the inside...same as the outside, and blown in ceiling.

BayRat,
I have both a 30'x40' and a 30'x60' metal buildings on my property. Be careful if you attempt to use that expanding foam in an aerosol can ... even if you get the low expanding stuff, it can "push-out" and deform some of your metal sufaces as it cures and continues to expand (which happened to me when I used the stuff in the building corners where I had a lot of open voids and air leakage areas). I ended-up using caulk to seal the small openings along the top and bottom edges of the corregated paneling ... and other than being somewhat labor intensive, it did the trick just fine, and caused none of the issues I had with the aerosol foam. Also, while I don't think mice "eat" the cured foam as a food source, I have had then chew through it.

yes, put the plastic between the insulation and the sheetrock. probably not so important in a pole barn, but in a house, plastic on the outside will collect condensation, and cause wet insulation, mold, and mildew - a sick house.

My understanding....
Where you put the vapor barrier depends on what type of climate you are in. You want the vapor barrier on the warm side. Outside of wall if you live in a mostly cooling climate or inside of wall if you live in a mostly heating climate or only intend to heat the building, such as a barn/shop. The goal would be to not have moisture condensing on the vapor barrier and wetting the insulation.
Anyway, I thinkyou want the vapor barrier on the inside of building.

I should have made it clear I was responding to bayrat's NY climate
Thankfully, a vapor barrier is relatively easy to install on the inside.

Anderson,
I didn't even pay attention to were bayrat lived. My fault. I just noticed some of the earlier posts about putting the vapor barrier on the outside.

Put the vapor barrier on the inside. The purpose here is to help prevent moisture from entering the walls from inside the structure (living area). It keeps normal interior moisture from penetrating the wall. Any moisture that DOES get in the wall should be allowed to 'breathe' to the outside (hence housewrap). I haven't heard anything about putting the moisture barrier on the outside in warm climates, but it's possible. Seems like it would defeat the purpose which is to keep human made moisture from getting into the walls. But, I really don't know much about hot weather environments. In SE Ohio, I would still go with putting it on the inside. Owens Corning has a good website with may pages of info. There is also a Vapor barrier page that comes out of the Univ of Alaska. These might be able to give you clearer info.

<font color=blue>So much good information now I think I'll have to sit down and do some price comparisons. That 8' batting sounds easiest but as mentioned, I would still have to put something up to hold the drywall. I had thought of using 1x3's but my friend told me that would compress the insulation too much. He thinks they don't make the thinner type that used to be used in 2x4 construction any longer, that is what I had planned on using. I don't know the answer, I'll have to find out when I start pricing. Don't know if the 8' batting would be more cost effective than the 24" either. Believe it or not, as ignorant as I am with this remodeling/building process, I shocked my carpenter friend when <font color=red> I came up with the two section walls using economy 2x4's idea</font color=red>!! Must be osmosis. Unbelievable winter here so far, only a few inches of snow has fallen all year.
