   In my mind? No good reason not to go with OSB.

   WOW!!! What a Ride!

   I know I'm probably in the minority, but for $5 per sheet, what's the price difference going to be, $100? I hate OSB. I hate cutting it. I hate moving it. I think ply holds fasteners better and I have more confidence in it retaining its integrity longer in damp conditions. I'd go with ply, but as I said, I'm probably in the minority and it's more of a personal preference kind of thing.

   Have you ever used Advantec? It is better than plywood in moist locations.

   Just trying to get this straight-- Advantec or Advantech? Truly I have never heard of the stuff before but if it has "tec/tech" in the name, it must be good. Also, how much does it run for a sheet?

   I've seen it spelled both ways, even on Professional sites.
   Now I'll have to look close at it tomorrow. I just sheathed a wall with the printing upside down today, LOLhttp://www.huberwood.com/products/dsp_products.cfm?doc_id=23

   You beat me to the Huber link. Used Advantech in my thread "Small Addition" I also used OSB for continuous wall and roof sheathing. Every thing was felted in before any rain. I used to swear by plywood, but quality control and quality of veneers has dwindled. Advantech is more like industrial particle board than
   large chip OSB.Chuck Slive, work, build, ...better with wood

   it is not the chip size so mauch as the phenolic resins and the process used to put it all together.

   Piff,

   Are you sheathing walls with 3/4" Advantech? Justin Fink - FHB Editorial

   1/2" on walls. 3/4" on subfloors

   I don't like either.  Advantech is my choice.

   The reason you have delta is in anticipation of or present knowledge of a damp or wet location.

   So I would use neither and get some Advantec. It is twice as good as normal OSB and probably half again better than plywood.

   I was a plywood diehard until my recent experiece building a barn for my workshop. I sheathed the walls with 4 ply 1/2" fir cdx, I couldn't find any 5 ply in my area, W. Mass. It warped like crazy as soon as it got wet. The Advantech I used for the 2nd floor and the roof sheathing has been much more stable. There is some edge swelling on the subfloor, but it's been flooded numerous times, as my progress has been a little slow. But still, no delamination and no warping.

   I'd go with the 3/4" TG engineered OSB.  Advantech or Weyerhauser Edge Gold.  I've seen reports and houses where theyve been rained on and soaked underwater and have not seperated at all.  You should be able to find some info on the net or from your lumber company pretty easy.

   Advantech.Flatter. More consistent thickness than ply wood. No delamination. Less deflection. Exterior resins. 50 year warrenty.Not to date myself, in the 80's delaminated FRP was a major issue in multi family dwellings.http://www.huberwood.com/dist_retailers/dsp_faqs.cfm?doc_id=216Chuck S.live, work, build, ...better with wood

   although a diehard for plywood having had bad, bad experiences with the "old" OSB i would recommend Advantech.  Have seen it get soaked and no warping or delamination.  For my money it would be the way to go

   I would use OSB over plywood. The quality of ply that we get is very low. It takes two men performing gymnastics to install T&G sub-flooring because the panels are so often warped. OSB may swell on the edges if you don't space the panels but ply has a tendency to warp.

   Ultimately, I would choose Advantech over both standard-grade OSB & ply. Advantech is stronger, straighter, and more in wet conditions than either sheet. Since you're installing Delta you expect some problems, follow through with a smart investment with your sub-floor.
