SubRay | Modular Radiant Subfloor System
SubRay Hydronic Radiant Floor Heating
SubRay™ is a safe, practical and easy way to install radiant floor heating over frame or slab floors. SubRay can be installed as a whole-house heating system, or used to heat a basement or room addition.
Modular Makes It Simple
A system of headers and sleepers make installation of hydronic radiant floors a simple matter.
Header Sticks hold radiant tubing at each end of the room and space it on 8" centers.
Sleepers are 6" wide (±1/8"), are installed 2-1/8" apart. They support the finish floor and provide a radiant heat channel for the tubing.
Radiant Tubing from Watts Radiant such as RadiantPEX+® or Onix™ makes the system complete providing clean, efficient and silent operation.

Thin - 5/8" or 3/4" thick
Lightweight - Less than 2 lbs. per square foot.
Moisture-Free - No hundreds of gallons of moisture to manage.
An easy installation - No need to wait weeks for the slab to cure. No scheduling problems with separate subcontractors.
Compared To Other Slab Alternatives, SubRay Is...
