Floor decking thickness


I need to deck an area in an unfinished space just so it can be used as storage right now. The joists are 16" O.C. 2x8's. What is the best thickness to use? the whole house right now is decked with OSB, I think its 23/32? is that too much for storage space or not enough? the rest of the house they have 23/32 osb then a 1/4" sheet of ply overtop of that glued and nailed down

Floor decking thickness


From my days as a carpenter we always ran 1-1/4" t&g ply for our subfloors. It's more expensive than osb but hold up much better over time.

That's gotta be pretty heavy huh? I'd be hulling this up a flight of steps

I used 3/4-inch Advantech decking when I built my house. It has a 50-year warranty against water damage.

guess 3/4 would be stronger then 23/32 since its slightly thicker, never saw their stuff though, its resin composit sheets? Any advantages of this over OSB?

I will have to remember this if we ever get to building a new house. Is the cost relatively close, or is it greater pricewise?

23/32 vs 3/4" (24/32)? Hmmmmm....that works out to 1/32" difference.....

I'm doing a 2-story addition right now....my second floor is 1 1/8" T&G.....I questioned it at first...but now....very glad....about par to walking on concrete.

Don't do OSB....it does not do as well as floor sheathing....OSB is better suited to shear walls.
