Thermal Mass: Heated Floors
Professional Thermal Mass Installation by Northwest Systems
Enhanced Efficiency for Radiant Floor Heating Systems
Northwest Systems is a family-owned, third-generation company with over 40 years of experience in providing high-quality floor underlayment solutions. We specialize in radiant heating systems, providing the thinnest and most efficient thermal mass available at just 1½" depth with excellent responsiveness.
Maximum Efficiency & Fast Response
Our thermal mass products enhance the luxury and efficiency of radiant floor heating, providing a fast responsive 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 starting at 2,500 psi up to over 4,500 psi. Our flowable floor underlayment is specifically designed to meet the needs of radiant heating systems.
Why Every Radiant Floor Heating System Should Consider Our Thermal Mass
- Heat Resistance: It resists heat deterioration and is specifically formulated for radiant heating systems.
- Enhanced Responsiveness: It improves heating system responsiveness due to its efficient thermal mass.
- Safety & Durability: It provides a smooth, tough surface and is fireproof — giving you a safer home.
- Structural Benefits: It stiffens the floor & reduces the bounce (like a laminated beam) and won't shrink or crack.
- Energy Efficiency: It seals perimeter walls, keeping out baseboard & floor drafts, as well as insects.
- Sound Control: It eliminates squeaks and nail pops common to wood underlayments and provides an excellent sound barrier between floors.
- Superior Heat Transfer: It maintains a direct bond with the substrate and tubing, resulting in very efficient heat transfer.
- Tube Protection: Its agents stop the PH acids that are found in concrete, ensuring acid doesn't damage any tubing.
- Lightweight: Its thermal mass is approximately 40% lighter than concrete, requiring less structural support.

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.
