Float two layers of 1/2" ran perpendicular to one another, fastening the top panel to the bottom with 7/8" staples. There are also interlocking subfloor panels that are designed to float, with air channel passages on the back side. I can't remember the name of them at the moment but I'm sure someone around here does.
Why are you adding plywood?
This is the direction I'm currently leaning. I'd like to offer another option with a thermal break but they originally said that they weren't concerned about the temp of the floor. Now that it's 5 degrees out, I'll see if they still feel that way.http://bostik-us.com/sites/default/files/MVP4.pdf
I have not done this but as discussed in another thread, you can glue right to the tile. It was suggested using slc to smooth the surface.

I have tested the tiles and they have very good coverage, which makes the terrible grouting a bit curious. The job looks like the HO had some decent subs in and then tried to do all the trim, grout, etc. himself.
So my takeaway is that my basic option is still Bostik MVP and then gluing the flooring and my better option is foam with two layers of 1/2" floating over it.
Any other opinions? Plywood recommendations?
talk about reinventing the wheel.
just float the damn floor..theres your thermal break and all other concerns eliminated

That would be nice. Do they make underlayments that don't sound cheap now?:whistling It's a million dollar home.
I was going to ask if anyone else finds the sound of a floating floor an issue. It screams "cheap" to me even though many times its not. Ive worked in a few high end homes with floating floors in basement. Never on par with the rest of the home.
