OSB vs sheet rock for garage walls.

I have seen a lot of guys use osb on the walls in there garage instead of sheet rock. What would be better for the garage would a guy really need sheet rock for the garage? Also what size of osb and sheet rock would you use for the walls? The ceiling is already done. I think the osb would be quit a bit cheaper.
 
I used osb on the walls that I wanted to be able to hang stuff on and drywall on the rest. If you don't like the redneck look, just paint it.

For insurance purposes you dont wanna use OSB. But it is the nicest for hanging shelves and all kinds of antlers/parts and boost bunny posters on...........
 
Fire purposes? LOL What do you think the trusses, the studs, the roof sheeting, the walls outside sheating is made out of in MOST garages? A garage is going to burn easy whether you have OSB or drywall on the walls. I would use 7/16 OSB, it is a lot cheaper and durable. If it gets wet, hanging stuff, or stuff bumping into it.
 
I'll have to check with code, i think the code only requires sheetrock on the interior walls and ceiling and that is already done.

Having drywall is required by code in certain places in an attached garage because it will provide extra time to escape the structure in case of fire.
My guess is that if it isn't sheathed already, you can use whatever you want.
 
Ahhh, got the answer right here for ya.

The walls that are ajoining the attached house to the man cave (garage) have to be sheetrocked AND fire taped. So the ceiling on my garage in the new house and a portion of the front wall in the garage is sheetrocked. Either ceiling has to be or the front wall has to be all the way to the top of the rafters..


I priced out the two for finishing the garage and decided to go with OSB. I went with the 7/16 from Menards here when it was on sale, like 5.98 a sheet, when sheetrock was 10+ a sheet for the saem thickness... Plus I like the fact that it will hold up a lot better than sheetrock in the garage, and won't have to tape and mud... and like they said, if you think it looks redneck paint it white! :beer;
 
Go with sheetrock!

Like others have said, OSB makes it look completely redneck.........

5/8 sheetrock has to be used on the attached wall to make the one hour fire wall.

Correct. Thats why anywhere my garage and house meet it is sheetrocked, and code is either to the rafters or the ceiling of the garage. Since it is more work and time consuming to go go around and cut it to fit to the top of the rafters, my contractor decided to go with the ceiling instead.

The OSB in my garage will be everywhere the sheetrock isn't, will take a pic tonight...

If it is painted it will not look REDNECK.


My dads shop is OSB and it looks clean. no taping, not texturing! all you do is put op the OSB and calk the seams and paint. looks nice. I have pics but can't figure out how to paste them full size from my comp without haveing to resize all of them.
 
My outside walls are OSB. Painted them white just like the rock wall.

One word, get extra paint. IT took me 3 coats to get teh OSB looking OK,and it could still use more. The OSB really soaks up the paint.

Also my old man has a shop with rocked walls, after years of the diesel truck living there the rock is shot where the exhaust dumps, also since it was the plow/work truck the garage was constantly wet in the winter so the bottom of the rock is crap as well. If you use rock, maybe a splash gaurd around the base and something where your truck exhasut dumps out.

My walls. Still need to do the ceiling, but the rock guy did bad work and the tape and mud is fallin off, so that needs to be fixed first.

sheating

its been funny watching all my neighbors mess around with taping and mudding, with little space heaters and messing around. I used 1/2 spruce sheating with 2 coast paint. done in a day. I will post some pics.

I'm speaking from code and an insurance point of view in case of accidental fire. Yer speaking from that cup of dumb you just drank. Of course trusses, studs and roof sheeting are going to catch fire. But thats why most states or provinces have a code of 5/8" drywall as "A FIRE BARRIER".
 
Here is what I know:
Bldg Code: There is a residential model code (IRC or International Residential Code) if adopted by your state becomes the State Residential Building Code. That code is the law as amended by your state. It becomes a statewide code but not usually enforced statewide (kinda like a speed limit with no cops in some areas). I will paraphrase… The IRC states that the wall connecting a garage to habitable space shall be covered with ½” drywall (used to be 5/8”) to the underside of the roof sheathing or to the ceiling if the ceiling and any wall that support the ceiling are drywalled. The joints must be butted tight or taped.
Drywall vs. OSB (oriented strand board): Currently drywall is more expensive. OSB is more resistant to water and rough use. OSB has far better nail/screw withdrawal ratings. Drywall is heavier. Drywall is far more fire resistant. Most would agree drywall is easier to patch/repair.
Opinion: What do you want your garage to be? A finished area for parking a clean vehicle, storing a snowmobile and lawnmower, and with a few tools that seldom get used… then drywall, tape, and paint it. It will look nice!
If you want to use it more as a shop where tools & ladders are being used, muddy or wet equipment will be in and out, and repairs and modifications are being done… then, other than the common wall, OSB the walls. It will last!
 
in my shop attacked to the house 5/8" fire-guard drywall as a base to the underside of roof sheeting, topped with 1/2 " plywood on the drywall or as you southners call it "sheet rock" , with 2 coats of high gloss white paint
