For Superior Heated Floors

Our thermal mass products enhance the luxury and efficiency of underfloor heating, providing a fast response to your heating system. It also provides excellent acoustics and results in a much quieter home. Listed by the ULC as fire resistant, it even results in a safer home. The thermal mass also makes for smooth transitions between floor coverings, as its height can be easily adjusted. When it bonds to the substrate the structure is stiffened, making it a stronger, hard floor with compressive strengths at 2,500 psi.

Maximum Efficiency

Thermal mass encases all of the tubing in a crack-resistant, noncombustible material. Some radiant systems install under plywood subfloors, but plywood is nearly four times more insulative than our thermal mass, resulting in reduced heat transfer. Thus, the thermal mass does its work above the subfloor more efficiently. This flowable floor underlayment is specifically designed to meet the needs of radiant floor heating. At a depth of 1½", it's the thinnest thermal mass available — so when the thermostat calls for heat, expect a fast response time!

Why Every Radiant Floor Heating System Should Consider Our Thermal Mass

  • It resists heat deterioration and is specifically formulated for radiant floor heating.
  • It enhances the heating system responsiveness due to its efficient thermal mass.
  • It provides a smooth, tough surface and is fireproof — giving you a safer home.
  • It stiffens the floor & reduces the bounce (like a laminated beam) and won't shrink or crack.
  • It seals perimeter walls, keeping out baseboard & floor drafts, as well as insects.
  • It eliminates squeaks and nail pops common to wood underlayments.
  • It provides an excellent sound barrier between floors.
  • It maintains a direct bond with the substrate and tubing, resulting in a very efficient heat transfer.
  • Its agents stop the PH acids that are found in concrete, ensuring acid doesn't damage any tubing.
  • Its thermal mass is approximately 40% lighter than concrete, requiring less structural support.
