Frequently Asked Questions
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.
Can all flooring goods be used over Thermalboard?
Yes. Consult the Thermalboard manual for the details regarding the application of flooring goods.
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.
Why is the tubing 8” apart?
How much does it cost to install TB?
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.
