Insulating pole barn with batts?

[mikhett]

I plan on insulating my 32x32 pole barn walls after studding out with 2x4s.With steel siding should I use a vapor barrier against the metal b4 I install my batts? Thanks

No.

Check out my build in my sig. I copied the way Morton buildings does it.

You want the vapor retarder on the heated side.

What are you using for interior wall covering, if any?

 

[mikhett]

Sheetrock.I will check out your build MR NERD!

I put studs between the post of my QSI (Morton type) building and then put 6 in thick by 24 inch wide bats between the studs. The biggest mistake I made was not to wrap the building in Tyvek or similar house wrap. The exterior metal is not sealed against air movement in any way. And yes the vapor barrier goes to the heated side.

look up tyvek failures. Make up your own mind. I have seen my share. A well taped poly vapor barrier stops the wind. IMHO tyvek becomes a second vapor barrier and then you have saturated insulation and rotting wood.

Bull nerd, I really liked the way you hung the insulation. Many around here just sort of hang it on long nails

Thanks, that's because I had no idea what I was doing! LOL. I bought the rolls from Morton, he tried to explain it to me how they hang them but he couldn't show me any pics. I did it the best I could based on his 30 sec. description.
