Actually I posted on this topic a few days back and got no reply. I thought Id try again.
I am interested in info on GP 7/8″ plywood from those whove worked with it. I understand its new to the market but I thought perhaps some of you may have given it a look see.
In Sept. Im putting an addition on my own home and thought Id try it out first hand. Any feedback is greatly apreciated.

What do you mean "got no reply"? Looks like you had a couple......

When I die, I'm leaving my body to science fiction.
Now don't be too hard on the boy. The first reply on the other thread was after he started this one.
It's not clear to me what the intended use is. The GP web site talks about it being a single layer subfloor system. Does that mean the 7/8" ply replaces 3/4" ply and carpet underlayment, or what? They also claimed some stiffness increases, relative to 3/4", that were quite literally incredible.
I thought it might be interesting for wall sheathing. It might be beefy enough that you could nail up HardiPlank and not have to worry about having to nail the ends into a stud while keeping the nails 3/8" away from the end. Or maybe roof sheathing in hail country.
From the ads I`ve seen its touted as a major upgrade in subflooring. Of course thats what GPs claim is...I was hoping someone posting here might have gotten a chance to work with it.J. D. Reynolds

"DO IT RIGHT, DO IT ONCE"
Don't know how this relates to the GP stuff but I've used 1 1/4" t & g ply before and although it like lifting lead sheets around a job site, it makes for such a stiff floor its like walking on concrete!
My thought is the thicker the better. I used a double layer of 3/4" t & g and a layer of 1/2" run perpendicular on my own home. I would have probably used the 7/8" had it been available?
Like you care huh? ;)

Did you glue the layers together or just fasten each layer soundly to the joists? Or some other approach that I haven't thought of?

Well, it's nice to see that some of my little eccentricities aren't as unique as I thought. Or feared.
"Thick plywood and plenty of it!"
Screwed and glued both layers...
