Thermalboard Compared to Concrete Slab

Thermalboard vs Concrete Slab Comparison

Compare Thermalboard to Concrete Slab Pour Systems

A concrete slab is a very old method for delivering radiant heat. The chief advantage is that the slab is part of building structure, thus a large part of the radiant delivery system is paid for.

Issues to Consider with Concrete Slab Pour

Performance Issues

Thermalboard is more efficient that a concrete slab due to less resistance and better heat transfer characteristics, as shown in lower supply water temperature data below.

Design Considerations

  • Response: A slab system works but is very slow to respond, creating significant control complications. It can not heat up rapidly or discharge quickly
  • Control: Setting your thermostat to one temperature and leaving it there for the heating system is no longer an option in modern, energy efficient homes.
  • Insulation: A minimum of R-10 insulation under the slab and sides are required unless you want to pay for years of thermal leakage.
  • Options: Due to the above issue’s engineers will sometimes specify an independent structural slab, then specify on top of the concrete a thermally isolated, quick responding and more energy efficient assembly such as Thermalboard.
