Aluminum plates can be installed between wood slats attached to the sub-floor and radiant tubing inserted into the aluminum plates. These build- your- own systems were popular until the advent of systems like Ecowarm. These types of systems do not have aluminum plates where there are curves, lowering overall system effectiveness. There is a long history of some aluminum plates systems making expansion noise…not good. Since the undercut groove of Ecowarm retains pipe tightly in the groove, it does not tick like some plate systems when the pipe expands in the groove.
Raupanel can make attaching some flooring goods to its surface problematic. Since Ecowarm is made of plywood it has excellent nail holding and screw retention characteristics allowing wood flooring to be nailed directly to the board and making it easy to install all major flooring types. In the case of Raupanel, the system is both expensive and expensive to install.
