The fastest, most effective under-floor heating. Just pop PEX heating pipe into the top channel and Radiant-Trak uses the thermal conductivity of aluminum (120 times that of concrete) to spread the water heat into your room. No space, weight, or installation difficulties associated with concrete or gypcrete. Also easy to use in walls, ceilings, and from above or below subfloors.
