So are you saying the advantech is a good choice for subflooring under tile?
Keep your plywood layers no thinner than 5/8"
The first layer must be at least 5/8", and 3/4" is better since it holds screws better if you're adding a second layer, but the minimum called out in the TCNA guidelines is 3/8" - up to a point, more is better. That guideline calls for the ply to be exposure 1 or exterior rated glue and have no face lower than 'C'. It's harder to find suitable thin stuff, but it is available. When using a second layer of ply for natural stone, that second layer needs to be installed properly. The major reason for the second layer is to bridge the joints on the first. Where two ends meet on a joist, when there's deflection between the joists, those ends act like levers, pushing up. By installing the second layer offset (1/4-span), those ends in the first layer are supported better, preventing the jacking and the screw bond between the sheets aids the between joist deflection as well.

This is awkward, but...
