The SmartTrac Radiant Panel Solution from Watts Radiant is a single-panel modular system designed to simplify and speed up radiant heating and cooling installations in subfloor, wall and ceiling applications. It eliminates the need for silicone and curing. As it is 80% lighter than thin slabs, it also eliminates the need for increased joist sizes and double plating. Using SmartTrac, installers can run longer circuit lengths and use one panel for the majority of jobs.
