Greg Cross, RayMagic expert, and David Cheek (drywall contractor, DMC Drywall) discussing best practices to install Messana #RadiantCooling  panels on the ceiling.

They both agree that the best strategy is to have drywall hangers apply the radiant gypsum panels under the supervision of Mechanical contractor that make sure the active panels are installed following the panel layout.

Professional hangers are specialized in drywall installation, are faster and less expensive. While the panels are hung to the ceiling, mechanical contractor can start the piping of the panels.

Once the active panels are connected and tested, drywall contractor can complete the ceiling with dummy panels (supplied by Messana).
The taping and finishing is performed just like regular drywall.
