Approved Tubing List
These are the tubing types/brands approved for use with Warmboard products.
Using a tubing brand from this approved list will ensure a silent interface between the pex tubing and the Warmboard aluminum groove. Installing other types of tubing may create a slight ticking noise as the tubing expands in the aluminum groove during operation. This unacceptable noise is created by the outer layer of the EVOH barrier rubbing against the aluminum. Design a silent heating system that you and your clients won’t hear; install only with approved tubing.

Notes about Pex Tubing:
Other brands of Pex Tubing may be acceptable. Please check with Warmboard’s Technical Department.
Silicone or other types of adhesives are not to be used when installing any Standard Barrier Tubing or Pex Aluminum Pex Tubing.
The use of nail plates is necessary to hold down tubing in channels. Remove all plates before the installation of finish floors.
*To confirm that the hePEX tubing is manufactured after 3/12/10, find the “NOT FOR POTABLE WATER” labeled on the tubing. Check the number that begins with the two letters (example UB13100330). The last six digits of this number should be 100312 or greater.
