How I insulated my pole barn

There's been a lot of interested (timely since winter is here) in insulating pole barns. I just got done insulating the ceiling and top half of the walls using recycled 2" polyiso rigid insulation with foils. I wanted to leave the attic space open for added storage and in case I need to work on my travel trailer. This is just one way you can do it, not the best, not the worse, just one way. I nailed 2x2's to the sides of the truss top chords and screwed the insulation to those 2x2's. This allows room for air to vent under the metal roof. I rented an electric scissor lift that fit between trusses and raised to 19 feet high. Also a pic of the double barrel stove I built

I did mine similar to yours, only I used mostly a double layer of 1.5" in the walls, some styrofoam, some rigid. The ceiling was done with 6" fiberglass. It was all covered with osb, except for the part above the double door, which was already done with foil faced rigid.

Since there is an air gap between the rigid insulation and
the sheet metal, are the edges sealed off or is it left open for air circulation?

Looks good! I've tried finding that recycled foam board here but everyone wants a fortune for it this time of year.

How'd you like the scissor lift? I'm considering renting one in the spring to put my ceiling up..

the insulation sits flat against the girts. So the air circulation is on the cold side of the insulation. Obviously I need to finish installing the insulation at the bottom half of the walls. Basically, the insulation forms a shell inside the barn.

The barn is 36' wide, 40' deep and 14' high walls, all with 12' wide lean-to porch on one side (40' deep).

The scissor lift was great. Was $95 a day rental and worth every penny.

Looks great, I have been trying to figure out how I want to do mine recently and this is a timely post for me. I assume that you have a metal roof and if so, is there any underlayment on the purlins? How are you handling the venting?

I had foiled bubble wrap installed under the metal roof only because I didn't know when I could insulation and didn't want condensation build-up.
There is 3" space between the insulation and the bubble/roof for venting.

Did you read the initial post or just look at the pictures... Everything you asked is there if you read it...

Yeah, I did read it. I obviously missed the metal roof part, but the venting is not specifically described. Thanks for catching me on that, it sure enlightened me.

Great post Mark.

Thanks! Glad I could help. Just so you know... I got called out for skip reading in a post the other day. I was told to pay attention... Not that it really matters but I guess I was just feeling cranky... Sorry.

The shop is looking really good Yuch.

Lots of lights is a very good thing
good to see you insulating and working on the walls now, much easier than when the shed is full :)

The heat will make the project go so much better as well.

Wow thanks for sharing this. I too am using recycled foamboard but mine is only 1 inch thick. Mostly using 2 x 8foot sheets. The combination of the foamboard and air spaces gets a lot of good insulation.just curious how did you come by your foamboard, what did you have to pay for it.? I paid on average $.50 to $1.00 for each 2 x 8 piece of mine.
I assure you I read and reread your descriptions of how you installed it but still not understanding fully, just me, I'm slow. So the Top truss chords are 2x6's?, and you nailed 2x2's to them to mount the insulation too. How much space is between the top of the insulation and the bottom of the purlins? What type of screws did you use, how long and did they have plastic caps? How are you mounting the boards in the walls, to the girls? Are you going to face your walls with tin or anything?
Great that you are using recycled materials, and again thanks for sharing!!
