Ok guys, here we go...


BUILDING:

Here in rural Ohio and currently have a 40x64x12 pole building addition with metal roof and siding. The inside is unfinished with exposed trusses 4'oc and bubble wrap between the roof metal and its purlins. Conventional truss, so flat bottom chord. 4/12 pitch. The exterior walls have no wrap, simply metal attached to side girts on 6x6 posts. It has a 16x10 and 10x10 overhead door, a 36" man door, and 7 windows, all double pane, double hung. Also, along one gable end is a lean-to whose "attic" space is open to the inside of the building. (Hope that makes sense)

It will be getting liner panels on the ceiling soon and eventually liners on the walls. I'm not going to do my own blown insulation up in the ceiling.. with trusses 4'oc and only one brace down the middle, I'd rather pay an Amish kid to do it. I'd hate myself if I had a misstep.
From here on out I'll call it the "new" area.

This building is attached to a 22x20x10 garage that is/was a detached garage, too nice to tear down so we punched out its back wall for a 10x10 overhead door and a 36" man door. This space, unlike the other, is insulated by previous owner and the walls and ceiling are covered in OSB. This area will probably be my paint booth. (I do custom bike work and occasionally some car parts roll through.) From here on out, I'll call it the "old area"


PRESENT STAGE:

I like doing electrical work, and for some reason I'm good at it though I'm no expert. I find it cathartic and I've been doing the electrical work in the new part in my spare time, biasing my efforts toward the trusses because once the liners are up, I plan on hopefully never going up there again. So I'm making my drops at the walls and stopping there, thinking that once the ceiling is up, I've got all winter to do outlets etc along the walls. But it sure would be nice to have the ceiling closed up. I lose so much heat out the soffit and ridge vent. (There's also a time constraint in this whole deal which would take too long to explain, but let's just say it would behoove me to have the ceiling up within the next 3 weeks)

I blast heat with my Mr Heater 210KTR torpedo... It's a monster and seems to actually help out a bit while I work out there.

I plan on finishing up the cable runs in the next couple weeks and putting up my roof baffles in anticipation of blown insulation going in.


PLANNING/CONSIDERATIONS:

The large new area will be for vehicles, light woodworking, tools, waste veggie oil storage, etc.. Hobbies in general.

I definitely want a safe, dry heat. Ideally, when painting, I should be pulling heat from the new area into the old, through paint booth filter blanket media, and then exhausting my fumes outside. So, I really shouldn't have to worry about solvent meeting flame and I plan on having the stove pretty far away. I also think the liner panels would help bounce some infrared out into the new area (2560 sft)
See pic below with my crappy markups. Pic is taken from proposed stove location. Center overhead door leads to old area (paint booth).

My old area (paint booth) needs heat of at least 65F if I want to have any luck painting. The warmer, the better.

I definitely want a wood stove, whether it's a barrel stove or freestanding EPA style with glass door on the front. I don't want to mess with the ceiling so the flue will elbow out and then go up next to the gutter outside. I'm going to have three 24" wall mounted industrial fans strategically placed around the perimeter about 9' high to move the heat around. They can be angled up and down.

I'm intrigued by radiant tube heat but I have no frame of reference and am not sure how much they cost. We have no access to a natural gas well here but having said that, I'm okay with having a propane tank out back. We had a propane heater at our old house for the 30x40 pole barn and it seemed to do a good job, although it wasn't great for me since it basically moved a lot of dust around. Dust does not belong on top of clear coat, don't get me started. But I worked around it.. I'd be open to that again.

I'm pretty sure I don't want to do spray foam insulation, mostly due to cost. Closed cell came in at around $12k for the whole building... Not sure what it would be if they only did the walls, haven't asked yet.


QUESTIONS:

See a pic below for a side view of an exterior wall... Should the ceiling and walls get a vapor barrier (5 mil plastic) between the wood and liner panels?

What would make for a good cold-day routine, get a fire going and while it's heating up, blast the kerosene heater? I figure that would give me some pretty instant heat and once the stove is going, it can maintain whatever desired heat level throughout the day. I have plenty of wood to feed it.

What do you guys recommend for wall insulation? In recent days, I've starting leaning away from framing out another 2x4 and thereby having a 3" thick space for R13 insulation. Instead, I'm thinking of going with flush walls since the cost of lumber would be about the same but would involve much less J channel which I'd need for getting around the posts. Besides, I don't want to see exposed outlets on the posts and, in fact, a flush wall with 5.5" of space to play with means I can essentially put outlets wherever I want on the walls.

What's better and more cost effective for 5.5" walls, big box store residential insulation or the huge batts they make especially for pole barns?

Any spray painters here? Would you guys do an outside air intake for the stove? Am I not as worried as I should be?


IN CLOSING:

if you made it all the way through this, thank you for reading and I look forward to any sort of input and ideas. Thanks guys!c21cd5526cffe77503891ffd407b4b5f.jpg302d5420031154f1e4e0d00ae680a5a0.jpg85ea6f98a369d9db9808cce498e310ed.jpg

Nice looking shop. I had a smaller 24x32 built at my last home. Also central Ohio. Had the builder insulate the walls and ceiling and finish the interior with the same sheet metal as outside. If I were to do it again, I would go with plywood on the walls for storage mounting etc.

I hung a small radiant LP heater on the wall by the man door. Only used it when I was in the shop. With the insulation the place was always above freezing even without heat.

I could start up the heater and let it run for a bit to warm up the space. Then it would be sweatshirt weather warm. Worked out for me.

I also did all the electrical in conduit on the surface just in case I wanted to change things later.

You may want to check with your insurance company about having a wood burner. I know a lot of people use them, but most insurance companies frown on them, if not outright just saying no to them. As far as your walls, what I would do if it were mine would get some 2x6's and stud the walls between the post. Or if you want the post exposed use 2x4's studs backed up against the girts.

Ditto, code here is that any exposed flame has to be 8' up in a building that stores vehicles. Common sense agrees with this, I've seen 2 big fires locally from WB stoves that took out big buildings, classic cars and put a guy in the hospital with 3rd degree burns. WB is NFW in my book unless you figure out a remote boiler system with the WB outside.

Don't try to heat the whole building, section it off into heated workspace and cold storage. Insulate the **** out of the heated area and leave the cold area alone. Propane will break the bank, I moved from a building because of the lack of NG but if that's your only choice I understand. My propane bill was $1500/mo at my old shop until I converted to waste oil, that changed to 2500gal/yr of WO. (5000sf insulated heavy truck shop, 17' ceiling) Forced air or radiant tube is the only way to go, forget anything ventless as it promotes condensation like crazy on exposed metal parts and tools. I'm 60 so I've been through numerous buildings with lots of different setups. I've never tried painting as cold as 65F, only hotter, usually as hot as I can get it.

From what I see in your pics, enclose the bay at one end of the building, drywall it, insulate it and you'll love it. Don't try to heat all the way to the roof, drywall under the joists and insulate above that. Plywood above the joists for added attic storage. A 30-45K forced air propane overhead furnace would probably do the trick and warm up quickly. A couple of skylights would be nice on the cold side.

Currently I have a 2400SF hobby shop divided in half, both sides heat and AC. I only heat/cool the side I'm working in. Heat stays at 50F on the side with the bathroom.

Good Luck, nice shop!

Thanks, guys.. All good ideas.

The funny thing about the wood burner is that I mentioned it to the insurance company when I informed them about the new building going up and the person I spoke to didn't even blink an eye. I'll call back and mention it again just to see if a different representative would say something else.

I'm still on the fence about leaving the posts exposed or at least having them jut out. If I let them jut out, I would simply put some white flashing as a cap over them to dress them up a bit. But the more I think about it, I'm pretty sure I want flush walls. Having said that, it is nice to have the extra floor space recessed back into the posts.

I had a drywall ceiling in our old pole barn, and that place had trusses 24-inch on center and I really did not like how it looked. I have 4 foot on center trusses here and I just am not a fan of a sagging and unfinished look. Besides, having the liner panels on the ceiling and the walls would offer very good fire protection.

I like your idea about the 2x6s coming out to be flush with the posts, but when I had the contractor out to look at the ceiling, he mentioned simply bringing some two-by-fours straight across from post to post and essentially having an open cavity back there. It seems like there would be too much flex, so I would probably stand up a 2x6 every so often just for a little extra support. And at the very least, have a nice vertical piece upon which I can run my 14/2, 14/3, 12/2 or whatever cable I need.

I can appreciate the anecdotal stories of wood stoves burning down nice barns and shops, but I would like to know the story of why that even happened. Was it a lack of clearance from combustibles due to amateur installation?
Also, I don't anticipate the shop being too leaky. All that infrared pumping off of a stove and a fan to move air across a 450-degree to 600 degrees surface would surely do the trick. (One would think!)
I have diesel vehicles so it would be nice to load up a stove in the evening and have a somewhat warm garage to come out to the next morning. I'm sure the vehicles would love it.


Once again, I appreciate you guys weighing in and giving me things to think about. I love hearing things from different angles and I hope some more people can weigh in. Let's keep the ideas flowing!

Oh hey I forgot to mention I might have access to a used boiler from a friend. Probably could be had for about $1,000. It's all stainless steel, a little bit beat up but I think it would work. My only concern with those things is that you're constantly married to it in the winter time and always feeding it with wood but then again it would only be for about four or five months here.

It would be simple enough to pour a little concrete pad and plumb the lines to a radiator inside. So I'm open to that idea as well. I think ultimately I should have multiple heating sources. And for prep reasons, a wood stove that we could cook on as well.

I'm not sure if Cleveland has a more stringent code than the rest of the country, but the NFPA code says 18" elevation for flames in a garage. Not 8'. But it may be overridden stricter in some areas. My dad had a large building subdivided into heated and non heated areas. I didn't like going between the two areas all the time. I built my 40x64 to heat the whole thing. Better insulation. The cast iron tools like that better too.

I had an old wood burner chimney on my shop from the previous owner (there was no wood burner inside, just a capped chimney). I got letters from the insurance company all the time "On a recent drive-by inspection, we noticed a wood burner chimney, yadda yadda, call us ASAP" etc. I got sick of it and removed it just to shut them up.
