Moisture proof insulation cement board

[dougstove]

Hello;
I have a memory of seeing a cement board or drywall product that had expanded polystyrene balls embedded within it, to create insulation.
Can anyone point me towards such a product? I am not finding it through Google.
cheers, Doug

Insulated wall panels? Home Depot: http://www.homedepot.com/p/Amdry-3-...96/204399265?N=5yc1vZbaxx#product_description

Looks a bit costly, but, it beats doing it the old way.

Do not use for hearth applications. Not rated for that.

Thanks for the information.
Not for a hearth; I want to add an insulation layer below an existing ceiling, and thought this might be a 1 step installation, rather than foam board covered with drywall.

Foam bead in the cement board are there more for lightening the weight of the board rather than for insulation purposes. A few different kinds out there, more of a density thing.
