The Watts Radiant SubRay radiant floor system is a convenient system designed to simplify the layout of radiant tubing in a radiant floor heating system. Compared to traditionally used thin slabs, SubRay is incredibly thin and lightweight (less than two pounds per square foot) and installs clean, fast, and moisture free. The floating design prevents noise due to pipe movement and temperature response is much faster than other traditional materials. These SubRay sleepers are laid between radiant tubing to space it out evenly as it covers a floor. High-grade Baltic birch is used for construction, giving these SubRay sleepers a long, reliable service life.
