Building a pole barn – Insulation for knocking edge off?

mikeysp | Posted in General Questions on

I am building a pole barn and will eventually pour a slab in it and have my wood/metal working tools setup.  Most folks around here, run “double-bubble” (Bubble wrap) between metal and purlins. I have only graded my pad (east/west) and want to mill up my lumber next week. Is there any advice you can offer for a pretty good shop..barn?

Zone 4A west of Nashville (Rain, rain, rain, humidity and more humidity).

    The double bubble may be good enough to keep roof from condensing and raining inside but not much more. On my pole barn I put a layer of polyiso on the inside over the walls and under the trusses that kept the wind out and provided enough insulation to survive on a propane-fired heater. I taped the joints. I also covered all of the wall insulation with OSB. It's not going to meet energy code and technically you should cover the insulation at the ceiling. There are other threads on trying to meet code in a pole barn.

    The topic of my next blog -- scheduled for publication tomorrow (Friday Feb. 8) -- is "Insulating Pole Barns." You might want to read that article after it's published.
