OSB is an acronym for "Old Shitty Board"
You need 4 sheets of whatever for that size room (8x16).. If you're going to be running a business, spring the extra 50 bucks and put in something that does not suck. You will have enough to think about other than if your floor is going to hold whatever you want to put on it steady enough. |

I wouldn't use it if you gave it to me. Every few years the breathless cries of "But it's been improved--this stuff isn't crappy like the old stuff!" comes up. Same shit, different iteration.

This and screwed and glued. Rock solid. |

OSB is crap.
3/4" T&G CDX is standard for 16" on center joists. Some older buildings have 4x joists 4' o.c., if that's the case you'll need 1 1/8" CDX. Glue the joists and gun nail down with ring shank 8s, 10s if you go with 1 1/8".

This is my answer as well - OSB sucks. |

I am a building contractor. I will not use OSB. I also will not use 3/4 T&G plywood from Home Depot or Lowes. They sell yellow pine 3/4T&G. The pine is affected by moisture in the air. Go to a real lumber yard and get 3/4 fir T&G plywood. It holds up better than the OSB and pine. The fir plywood from a real lumber also generally has more layers than the T&G from Home depot and Lowes. The extra layers make the plywood stronger and has less deflection in-between tho joists. I would use a sub-floor adhesive with 8P ring shank nails . If you use screws don't use black drywall screws, use a decking screw.

Nope. I've done it several times. For some reason, the really cheap sticky tiles seem to stick better to OSB than the nicer Armstrong ones. Fine the clearance $0.28/piece ones at Home Depot and stick away

3/4" T&G OSB is pretty standard for floors around here. Generally, a decent company will glue it to the joists to prevent squeaking. It's fine. Hell, i used it on for floating floor when I expanded my retail shop. Part of it I carpeted, and the rest I put sticky tile right on top of. 3 year later and someone else is leasing the building and using it now 
I only see the better custom builders using real plywood for floors. Speed Did you have any problem putting the sticky tile over it? Nope. I've done it several times.

Speed Shit is going to stick to OSB because you are gluing glue to glue.

Strange how the same lumber company sells wood to the local Home Depot and the local overpriced lumberyard. Sometimes the same truck delivers to both places. Home Depot sells 15/32 in. 4 ft. x 8 ft. CDX Fir Plywood. |

Look into advantech. Its is like osb with some kind of coating that makes it water resistant. They use it in residential flooring, boats and trailers. Advantek FTMFW Been using it for I can't remember how long. It's good shit. With all due respect to the above posters they don't know what the fuck they're talking about. I'm sure none of these "experts" have ever seen (insert brand here) 3/4 t&g plywood delam either. |

osb on floors hell no plywood all the way osb sucks on floors pretty much anywhere carpenter here for many years osb does not hold up FIFY I wouldn't use OSB anywhere, for any project where I had any say in the material selection. Let it get wet, or even damp, in a situation where it can't dry fairly quickly, and it'll swell up for a while and then revert to the splinters and flakes it was made with. |

If you have any type of humidity at all, you will replace the OSB in 5-10 years , maybe sooner. Don't tell me it's waterproof, between the moisture and the traffic it'll come apart.

I would go with tongue and grove Georgia Pacific DryPly 3/4" Plywood. In my opinion it's the best subfloor out there. That's what I use on nearly every job.
Most builders around here are hung up on Advantech OSB. It's supposedly has a 120 day exposure no sand guarantee now, I think they've recently upped it. |

The last home i built went for close to 500k. i would not use it in florida. the salt and humidity would destroy most osb i will take 3/4" tg douglas fir plywood any day of the week. |

I used this in my boat when I remodeled it. It will hold up to indirect moister, but an underpayment would be needed for the tile. |

We're opening up a retail shop in the next few months. I've been given a building that we can remodel and use. I need to re floor the building. It's not big (16ft wide 8 ft long I think) and was wondering if OSB would be ok for flooring. We're planning on putting down vinyl tile (the sticky kind from lowes) after the flooring is finished. I've read mixed opinions: some say OSB is ok, but plywood is highly recommended. Any thoughts on using osb for flooring? At $37 a sheet for plywood, it's eating up our budget quick. OSB is a lot cheaper, but is it sturdy? 16'x8'? That's not a building, it's a room. It's not really a room, more of a cell. 4 sheets of plywood. $150 with tax? $60 difference between plywood and OSB? There may be a time to shave pennies, but this isn't one of them. |

I think I'm going to just fix that spot and bleach the hell out of the floor to get the odor out. |

Self stick tiles will not work well on OSB. You will need a smooth
underlay for the tile to bond to. |

OSB has no structural integrity whatsoever. Plywood does. Couple that with the fact that once it gets wet it essentially turns into sawdust(it's basically sawdust and glue) and you get the idea. Use the tng 1 1/8 plywood this is what we use for pier and beam floors that have heavy loads. We also put the floor joists every 12" .Its easier to spend the money now than to have to go back and redo it . It obviously costs more to do it twice Not to mention damsge to equipment if there is a catastrophic load failure. 20 years exp.
