Has anyone used Rehau Raupanel Radiant heat system?

Has anyone used the Rehau raupanels in a radiant floor heat system with wood flooring on top of it? The aluminum panels do not fasten down to the floor, and I am worried that they will move and make noise as the floor is stepped on. Has anyone encountered this? I have only ever used the quick-track plywood panels which are glued and screwed to the floor.
Thanks,

The two best radiant systems to install are either Warmboard (they now manufacturer a system to install over an existing subfloor), or rau panel. The raupanel will not make noise when you step on the floor, you won't even know it's there. For efficency comparisons, and what's best for customers, no other products come close.
