Easy Installation with Thermalboard

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

High Performance

Thermalboard installs directly below your finished floor, allowing the highly conductive aluminum to deliver heat quickly and efficiently.

Superior Responsiveness

Thermalboard is far 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 project using conventional practices and tools resulting in a smooth installation process.

Lower Operating Costs

Thermalboard’s high efficiency means lower operating costs over the lifetime of the system.

Low Profile

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


Thermalboard is very lightweight at only 2lbs / sqft making it easy to maneuver and install.

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 Sustainable Substrate. No VOC. Zero formaldehyde.

The substrate is constructed from 92% pre-consumer recycled content and meets LEED® v4 Criteria, with zero formaldehyde and no VOCs. Additionally, Thermalboard is laminated with aluminum which does not permit the large formaldehyde molecules to pass, even if formaldehyde were present.
