30x48x14 pole barn

12x30

8' on center poles 6x6

2' on center 2x4"s

Let me start out by giving you the specs of the building. 30x48x14. Back section has a 12x30 loft. 6x6 poles 8' on center. 2' on center truses.

This is my dads building. We're going to put up a wall down the center and have 2 separate bays. One will be a workshop with a hoist. The other side will be a clean room where I can detail cars. I'm 20 and he's looking to help me out. I've been detailing on the side for Over a year now. I work 60 hour weeks at a full time job and detail cars after work. I'm hoping to open my own business someday. Anyway let's get to the point.

My main question is how should we go about insulating this? I've read a few threads but didn't come up with too much. We're from Michigan. We see -10 temps easily in the winter. But normally not that cold. My dad thinks some 1 1/2 foam between the 2x4s with some osb and steel over it will be good but that doesn't seem like enough to me? What do you think/suggest?? We're on a budget so spray is out of the question. We want cheap but good if that's possible.

We're also looking at options for heating. Both sides will be heated but my side more often. We're wondering if one big heater with ducts running through the roof going to both sides would work or two smaller heaters would be better? The heaters will be natural gas.

I appreciate any help you guys have. I'm just trying to figure out what's best. Thank you

Josh,

Welcome !

Do you have any pics? I am looking to build a new shop the size of yours. Right now I am thinking of either a loft of full upstairs. Tell us where in Michigan you are, and others may be able to give better info. It's possible there may be some members close to where you that can recommend insulation services, etc.

Thank you! I don't have any pictures at the moment but I will try to get some. I'm in west Michigan. The Zealand area

What do you guys think?

 

[mrpizza]

I would spray foam it. The professional jobs come out great and are excellent at insulation.

How thick? And what would something like that cost?

 

[socapots]

I think your best bet to finding out prices is to call around locally. Spray will be the most expensive route.
You coins also do batts and vapor barrier.

Start watching your local Craig's List for insulation, people have extra all the time. Start installing batts and cover with OSB or drywall as you get a section completed. Do it yourself and save your money for a heat source.

Horizontal or vertical bats? And if I do bats do I need to instal foam between the 2x4s?

 

[SALIV8]

I just had my pole bldg built in fennville, Mi. If you want a referral let me know, the amish GC crew I used were down right excellent.

Can't help you on the insulation, tho. when I called around for spray foam the price varied but will be about 3-4g if I remember correctly.

Yeah that's what I was worried about. 3-4g is too much for me. Does anyone know the answer to my question in the previous post? Horizontal or vertical bats? And if I do bats would I need to fill in between the 2x4s with foam?

I'd install batts between the 2x4's, I'm assuming from your description that these are the wall studs.

No this is a pole building. No studs. I'm talking about the 2x4s connecting the poles together. On the outside of the poles where the steel atatches. Anyone have any ideas for me? Looking to do this soon! Thank you

 

[Tazzie]

The biggest thing to think about in a pole building is to seal it up and make it air tight. Fiberglass will not do that spray foam will. I am in Michigan also and it get very windy in the winter. Good luck on your build.

 

[pmilin]

Are 2x4's big enough for the side girts. Seems like they will twist and bend to much. 2x6's might be a better choice.

 

[bullnerd]

Pole building insulation that comes in large sheets.

See my build in my sig.

 

[bazzateer]

Regarding the heating I'd look at two smaller heaters for each side. You don't want to be running heat into an unoccupied area.

This looks good! I like that idea. Where did you get that from? And did you fill
In between the outter 2x4s?

 

[socapots]

I don't think you would need to fill between those 2x4s.
if you can fit R20 in there go for it. Doesn't all have to be the same kind.
Do it vertical vapor barrier, and strap it with 1x4s or something that will keep it in.
You could sheet it in osb. But that might be more money than its worth if you don't plan on hanging anything of it.
Figure out how much you need. Go on some local stores websites, like home Depot or Menards. Price it all out. Then see if you can find it cheaper used. Our leftover stuff from other peoples builds.

 

[josh825]

Really leaning towards the way bullnerd did it. Would it hurt any to stuff some foam in between the 2x4s while I'm at it? Also, if I take it right the plastic/vapor Barrier goes on after the insulating between the steel/sheating?

 

[Diesel Dan]

My main question is how should we go about insulating this? I've read a few threads but didn't come up with too much. We're from Michigan.

Many ways to insulate.
Here is what I used as a option:
-Johns Manville PEBS blanket, P19925
-92.5" wide x 40' long rolls.

After hanging insulation stapled up vapor barrier then another row of wall girts and steel on the inside as well.

What R value is that? And how much a roll?

[bullnerd]

Hey Josh, Sorry, just saw this.
Im no pro by a long shot, Im just copying how Morton buildings does it.
I did not fill in between the 2bys. I have a phobia of the insulation sitting up against the metal...on either side. The rolls are aprox 8ft wide(forget the exact width)and 40ft long by more than 6in thick, plenty for me. I actually bought it right from Morton here in NJ. The guy I contacted waited until they had extra rolls from other jobs then gave me a great price. All the info is in my build thread. I'm really dragging my heels on it lately though. Waiting to buy a drywall lift to start putting the metal ceiling panels up. Search for pole building insulation in your area, Ive seen guy mention it on here. Good luck, I'll try to answer any other questions.

EDIT: Im a *******...I didn't notice the second page! DOH!

 

[Diesel Dan]

R-19, 6" was ~$130/roll IIRC.

Thanks to bullnerd for giving me the idea of the PEBS blanket!

Ceiling steel in 10' lengths can be done with one person, scaffold and a wooden t-brace. Or just rent the drywall jack for a day or two.

Hold on a minute there Baba Looey! There's much more to your question than what type of insulation!

So you want your detailing bay to be a clean room, separated from your dad's workshop bay. Will both bays be heated all winter, or only yours? Will each bay only be heated when you guys are out there? What you do is completely different depending on these answers.

If both sides will be heated all winter, you don't need any insulation at all between bays. Just build a stud wall and install OSB/drywall/plywood/metal liner, seal the top and bottom to keep dust out and you're done.

If only your side will be heated all winter, but your dad's side only intermittently, you need to insulate your bay as a separate structure, with a proper vapour barrier depending your climate zone.

If both sides will only be heated intermittently, you're back to not needing an insulated wall, just a dust sealed wall. How do you plan on using the space?

 

[josh825]

For now only my bay will be heated. My dad has another smaller garage that he's got heated and can work on most smaller stuff in there. So I plan on insulating the center wall. How do I find the correct vapor barrier since my bay will be heated sometimes snd the other won't be?

 

[Diesel Dan]

Could you use unfaced fiberglass batts with tyvek on both sides of the wall??
