Insulating a room in a pole barn?

[tom4018]

For lack of a better term we are building a man cave in a garage/pole barn. Metal siding that has the double bubble reflective insulation behind the metal. Was planning on framing out walls in between the posts and finishing off a room. I was wondering is un-faced insulation would be best? I was think the insulation there next to the metal would be a vapor barrier and if I used a faced insulation that moisture might get trapped in between them.

Am I thinking wrong? Any builders out there that might have some suggestions?

i would use polyiso sheets. i wouldn't do fiberglass in a metal building.

ISO is best insulation. R factor is 6 per inch.

i put 2" thick sheets commercial grade underneath my houses metal roof. It feels so good in the house.. hardly ever have to use the A/C or heat. extremely comfortable.. never know what the weather is unless you look outside.

What would you do if it was already framed out?

Not being familiar with ISO, I looked it up. Seems you can be some that was a removed from projects in various cities. http://www.repurposedmaterialsinc.com/poly-iso-insulation/

I can buy new for close to those prices.

Will that create a moisture problem with the bubble wrap under the metal and the iso in the studs?

Your bubble wrap will act as a moisture barrier to keep ambient air out

Speaking from experience....Spray foam.
