Want are you guys going with for your walls.Garage is 30x35, 10' walls.
OSB or Sheetrock?

What are some idea to insulate a ceiling that is spaced 24"apart.I have the pre fabbed gables.I was thinking those 4x8'sheets of insulation.There is a guy that selling a bunch on Craigslist for 5 $ each.He has about 20 of them.He says they are a 1 1/2 thick.Any suggestions?

I am also trying to stay on some type of budget.I am trying to get the best bang for my buck.I blew the budget on the initial build.Long story so now I am trying to pinch pennies here and there.

OSB would make a stronger ceiling or you could use thicker drywall there because of the 24" spacing. By the way, I hate finishing drywall! Then I would use blow in insulations piled deep. Put a moisture barrier on the inside of the insulated wall. Ventilate the attic above the ceiling insulation year round.

Hopefully your pre-fabbed gables are spaced fairly regularly. If not sister a 2 by 4 to them at the joints of whatever you decide for a ceiling.

Ligoomba...Welcome to Garage Journal.

One of the two hottest topics on this site are "wall coverings" and "Paint". Do a search for Drywall or OSB and you'll come up with half as many replies and scenarios as there are members. Not to dissuade you, but drywall, OSB, metal, pegboard, paint and such is "The beating of the dead horse" around here.

Don't take me wrong as I'm not trying to block you from asking, but I'm trying to keep you from going crazy deciding after you get done reading all of the replies. When it's all said and done, you still won't know what to do.

If you look through the gallery, and you already know what you want your garage to look like, then you are halfway through the battle. If you get pissed and throw wrenches, put up OSB. If you are the type that throws wrenches and walks around wiping your hands on the walls, DO NOT paint the OSB. If you throw wrenches but have a calm enough attitude to touch up any marks you make, PAINT the OSB.

If you want your garage to look like the inside of your house, don't have an attitude, then by all means put up drywall. If you are the type that has an attitude and want to run your fist into the wall, disregard OSB as you might break your hand, put up drywall, paint the drywall, then patch the fist holes.

If you want it to look like the inside of your house, but don't know how to hit a stud after you paint the drywall, put OSB up first, put drywall over it, then p[aint the drywall.

If you do not know how to find a stud, want your garage to look like the inside of your house, but want to hang anything anywhere, then put drywall over the OSB, but only if you are a responsible drinker in your garage and can remember there is OSB under the drywall.

Or go with steel. You have galvinized, corrugated, painted, long sheet, short sheets used as wainscotting, rusted, rusted currugated, rusted corrugated used as wainscotting, rusted with paint.

Then you can use steel over drywall, steel over OSB, steel wainscotting with OSB above, steel wainscotting with drywall above, steel wainscotting with drywall over OSB above.

DO NOT use PVC airlines anywhere, or members will read you every aspect of safety standards that has ever been wrote for PVC line from A-Z and then some. Also gray bottom with a white top for wall paint with a stripe of your choosing. Myself, I have corrugated steel wainscotting with maroon walls, a white stripe and a black ceiling.

Have fun, take a break for another beer after reading through every half a dozen threads or so, check in the mirror to make sure you still have most of your sanity, and above all if you don't already know.........WE LIKE PICS!!!!! The more pics the better. Pics of wife or girlfriend are always welcome, pics of wife or girlfriend swinging a sledgehammer or running a power nailer are good too. Bonus points if you have pics of wife or girlfriend up on roof using a power nailer. :rocker:

Oh, and BTW........Pics, pics, and pics!!!!!

And again...WELCOME!!!! :hellobye:

Thanks for all the reply's !
Which is cheaper ? Drywall or OSB ? Seems they sell it ,OSB on Craigslist for 8.00 a board all the time.
As far as the air .... I'm going with 3/4 copper lines.
This is a shop/garage that I going to use......
I'm a big car guy / drag race mostly, so lots of cutting grinding, welding ,engine building and I will be doing a little restoration work here and there for some extra income.My last garage was insulated but had OSB where I had my bench and I had another wall which was Sheetrock.
I kinda of got used to the OSB.
If they pop up on Craigslist again I'm gonna jump on it.8.00 a board no tax
Like I said I'm trying to be as economical as possible.
Has anyone used the insulation boards on the ceiling ?
I don't throw things nor do I punch the wall .I take a deep breath walk away .If I'm that pissed off I shut everything down and come back when I calm down .Its not worth it!!!
Pictures of wife,LOL ! I will try ! May be the girlfriend ;). !!

I think your last post answered your question. I think if mine was a working garage as you have stated then it would be OSB. No doubt its not as pretty as drywall but it does have its advantages.
I am considering covering my walls and I think it would be OSB. I cannot keep my hands clean enough in my garage to justify drywall.

I did both....OSB on the bottom for durability,(painted grey) and 1/2" drywall on top, ( with white primer) for a cleaner look & more light reflectivity...I put a red stripe between the 2 with a 1x4 over the joint, and in the corners for a more finished look without all the mud & tape in the corners...works for me...I mostly do fab & mechanic work on motorcycles...Shawn

Remember that you need a fire rated wall between your house and garage. You can put anything you want over or under that.

The builder sheet rocked and painted both of my garages and I was sure I would hate it. Turns out it's not so bad and if it does get scuffed up it would be easy enough to repair. Mine is 10 years old and still looks pretty good.
As far as insulation I would recommend blown in in the attic. Just make sure it is vented.
Just my $0.02 ymmv.

I'm in the process of putting up OSB in mine, then when I have the money I'm going to unscrew the top two feet and blow in insulation behind the OSB. Also OSB on the Ceiling with blown in Insulation. I just think for my use doing metal fab, old car and bike building it will be a lot more durable as far as being hit bumped against and hanging things on it. However someone that wasn't going to be doing things were it may get bumped and hit then Sheetrock may be the way. But for me OSB was the ticket. Will prime and paint the bottom 4 foot grey and the top 6 foot and ceilings white later.

Another vote for sheetrock. Primarily due to aesthetics.

Had a friend who did his whole space in OSB. Didn't look so great, even after painted. But it was functional and fit his budget considering he got most of it free, or dirt cheap. Even he agreed that sheetrock would have been better had the circumstances been different.

Another option...although I am not a fan of pegboard, the guy I use to tint my windows has a 60' x 80' shop on his property where he does the tint, tinkers with race cars, etc. He put up white pegboard. He does store a few things on the wall, but hasn't went all crazy with it. He seems happy with it.

I did the top 8' of my walls with OSB painted white and the bottom 2' with treated plywood so I don't have to worry about moisture in the walls if I pressure wash the floor or something floods.

$8 per sheet of 7/16 OSB is retail, or a little higher. Check the price at HD or Lowes before you buy on Craigslist. Also use deck screws to install it and not drywall screws. You will break the heads off a bunch of drywall screws if you try to use them.

8.00 isn't bad...its retailing for ~9.50 a sheet here currently..

OSB is like oil...prices are all over the place based on weather, magic 8-ball results, etc...
Last summer I was getting 7/16" ZIP sheets for 7.00 a sheet...today its 20.00 a sheet.

Geez...you guys, it's just a shop! If you sheetrock **** them together and paint em...screw the mudding...looks just fine for a shop. OSB great when I want to screw something to the wall, or if I want to move it I take the screws out and put it somewhere else. This pic has one wall sheetrock (wall with door)cause it was cheap at the time and it has no mudded joints, just paint. the other walls are OSB cause it was cheaper then sheetrock up here right after Katrinia hit and all the sheetrock was going south...all painted white to reflect light. If I did it again, I would use all OSB :D

Take a hole saw, bore a hole in the bottom and bore a hole in the top between each stud. Blow the insulation from the bottom. Once you have everything blown in, cover it with some 1"x4" trim boards.
