How to insulate a pole building garage.

[mdale]

Hi, I moved into my house a year ago and am starting to work on the garage. It is a pole building and the previous owner put r-11 fiberglass rolls on the wall and then put paneling to cover/ for walls. The paneling is dark and does not look good so I want to put up OSB painted gray to brighten up the garage and so I can hang lightweight items on the wall. My question is how should it be insulated? I would like to be able to leave the roll insultion for ease and cost,or should I rip it out and put 1.5in foam board insulation inbetween the 2x4's? If I reuse the insulation should I put the OSB up like they had the paneling ( squeezing the insulation down) or put 2x4 furing strips over the original 2x4's?
Thanks for the help and hopefully someone has had this problem before.

My neighbor used roll insulation with OSB and it looked good. He had a old house furnace and a 24 inch exhaust fan he used when welding.

So did he have the ext. steel, the horizontal 2x4 on the inside to start with, then roll the insulation over the 2x4's and squeeze it down with the OSB? I'm just trying to make sure I'm doing it right or somewhat right.

thanks

I insulated my barn last winter. I put rolled R-13 on the walls with osb over that. R-60 in the ceiling with osb over that. Just had the ceiling painted and decided the walls didn't need it. When it was in the 90's with the doors closed, I had to put my t-shirt back on. Nice and cool.

hey Bobby, is your barn a pole barn or do you have studded walls?

This sounds quite familiar. I too moved into my house about 9 months ago and went through most of this. The DAPO used barn siding on the inside of a 24 x 40 room and stained it a dark dark brown. I hated the darkness of it. I'm in the process of painting that stuff white, but the remaining 40 x 40 room was only insulated with the pole barn insulation wrap stuff. I studded in my walls with 2x6's and insulated and covered with drywall. I'm still working on it but I think it is working out nicely.

I used 4x8' foam board laid sideways and then framed with 2x4's with traditional studs spaced 16" apart with dry wall on top. Hopefully a friend will chime in here as he did the similar.

I'd be real careful about what you use do to the mold possibility. The metal and condensation etc. Lots of good threads on this subject here and elsewhere. I'd try the search function here, just to be sure what your thinking about doing works for your area.
I am still at a lose about which way to go on my pole building.
Considering spray foam as well as rigid maybe DBF (double bubble foil)

Good luck keep us informed.

I'm not preaching or anything, just curious, but why is it that so many people would rather put a combustible material on the walls like OSB, plywood, T-111, or wood panelling, instead of drywall? Especially if they do work in the garage that can ignite something such as welding. The cost difference is minimal, & drywall is fire resistant. There is a thread that someone posted in here about how he burned down his garage & his interior walls were bare framing without drywall. I understand that the wood will allow you to attach cabinets, shelves, & hooks virtually anywhere with ease, but finding a stud isn't difficult. Taping the joints is a pain too, but I think it's worth the aggrevation to be safer.

One last thing, if you did have a fire & had used a combustible material instead of drywall, would your insurance company tell you that you didn't build it according to code & get out of paying you?

MDALE- It's a pole barn but I did stud the walls. OSB doesn't have to be painted, it's stronger than drywall and I do all of my welding outdoors.

Bob, no offense taken. I think in many cases the choice to use OSB is because A) you can hang shelves, hooks, nails or whathave-you without worry that you have to hit a stud, b) you don't have to tape it, and c) the cost is on par with sheetrock. These were the reasons I went with it.
As far as code goes, in the case of my detached garage, I don't believe there is a code mandating a specific interior sheathing. On an attached yes but I don't believe it matters on a detached. I hope I don't have to find out but I'd argue a coverage denial based on OSB interior sheathing as opposed to the bare studs I had before.

Another reason I can think of to use OSB is durability. IMO drywall is too easy to accidentally put holes in in a shop environment.

I have a pioneer pole barn ... i used (doubled) r-13 in the walls uncrafted, than 2x4s running horizontal and a plastic over that for vapor barrier , iam going to put 5/8 sheet rock over that. It should stay toasty all winter with minimal heat.

How thick of a cavity is r-13 supposed to be used in? It is only effective as long as it is allowed to expand to fill the proper sized cavity. Squeezing it down really reduces its effectiveness.

 

[mad57]

i had almost 10 inches to fill the r13 is 3 1/2 so i was able to put in double with the (squeeze) and still have air flow around the stuff. pole barns are great for that.
