Differences In 3/4" OSB Subfloor


A local big box store (green one) sells 3/4" 4' x 8' T&G OSB in various brands. Their unbranded version is of course the cheapest and just called Sturd-I-Floor at $13.50, the next step up is PointSIX brand Sturd-I-Floor at $17.50.

Hoping someone has used both and can tell me what the differences were?

I have only used Advantec ($$$$$) and PointSIX ($$$$) but would like to use this cheaper stuff if it's all the same company just not getting branded and price increased from that. I was happy with both Advantec and PointSIX.

I am not sure of the differences, but look up their respective span loads, etc.

Re: Differences In 3/4" OSB Subfloor


a prime place to go high quality material, glued and screwed install, over under spanned framing is the sub-floor.

virtually impossible to fix a poor quality material or a low budget install.

will eventually ruin you....

The problem with the higher grade T&G OSB is when the edges swell they really really suck to sand. It’s almost like sanding concrete. If you do buy a top end sub floor, get one with a sand guarantee and be ready charge the manufacturer when you have to sand it.

Advantech is pretty good (in my experience) about paying for decking that needs sanded.

Any commercial flooring sander will knock it down with zero effort. But with Advantech youd have to leave it exposed a long time for edges to swell.

The one I rent must not be commercial then. It takes the regular grade down like butter, the no-sand warrantied osb not so much.

Re: Differences In 3/4" OSB Subfloor


Unless you are in the entry level homes/shacks or cheap apartments, IMHO 1.25" OSB/plywood is a NO BRAINER for added quality at a tiny Sq. Ft. cost.

In a "cheap" apartment the thicker floor is going to provide quieter units, All other things being equal, and lower long term floor covering costs....

If you can use wood trusses at 19.2" or 24" centers, you save even more $ on MEP labor as fewer trusses = less drilling and easier venting....
