Will Durock or other cement board atop subflooring provide sufficient
thermal mass for radiant floor heat?

I initially had planned to staple up the tubing with heat transfer
plates beneath the floor and between joists. Now I'm thinking of
putting the tubing on top of the subfloor and build up the spaces w/
durock with a layer of durock on top for tiles.
