Easy Installation with Thermalboard

See the installation of a Thermalboard licensed product in a major remodel.

Superior Performance

Thermalboard installs directly below finished floor, high conductive aluminum results in high heating efficiency. High efficiency means lower operating costs for years to come.

Superior Responsiveness

ThermalBoard is many times more responsive than a cementitious thermal mass; providing quick heat up, avoidance of over-heating and greater zone control.

Conventional Construction

ThermalBoard is installed within the natural flow of a construction projecting using conventional practices and conventional tools.

Remodel Friendly

Thermalboard is lightweight and low profile making it ideal for remodeling and retrofit projects.

Low Profile

Thermalboard has a very small 5/8 “ profile making it ideal for retrofit or remodeling applications.


ThermalBoard is very lightweight, which can be a significant factor in raised floor spanning calculations.

Here are some questions that often arise. Feel free to call us any time with any questions!

What kind of radiant tubing should I use?
One should use standard 3/8” barrier PEX tubing from any number of manufacturers. Do not use PEX-AL-Pex as it will become an oval when inserted in the grooves instead of rebounding to fill the slightly undercut grooves in Thermalboard. Standard PEX will expand into the groove creating a strong, silent connection enhancing thermal transfer.
Who should install Thermalboard?
Thermalboard is typically installed by the general contractor with basic carpentry skills. A licensed radiant floor heating mechanical or plumbing contractor should install the heat source, distribution piping, pumps, controls etc.
When is ThermalBoard installed?
ThermalBoard is typically installed just prior to the installation of finished flooring goods. Store ThermalBoard on the job site in a dry, cool space and it is ready to be installed with delays, in the natural progression of construction.
Can all flooring goods be used over Thermalboard?
Yes. Consult the Thermalboard manual for the details regarding the application of flooring goods.
Does Thermalboard outgas formaldehyde?

Thermalboard substrate: Super sustainable. Zero formaldehyde released.

Thermalboard is manufactured with sustainable post harvest rice straw making it completely sustainable and does not outgas formaldehyde because there is no formaldehyde added in MDF straw board. Additionally, Thermalboard is laminated with aluminum which does not permit the large formaldehyde molecules to pass, even if formaldehyde were present.
