Performance Issues

Unfortunately, Warmboard feels the need to exaggerate their good performance utilizing an in-house testing methodology used by no other manufacturer in the industry. This methodology conflates fast response time with system efficiency which is simply not correct.

They have good performance, just not as good as they promote. Side by side testing of many radiant systems conducted by Virginia Tech University, demonstrate that Warmboard and Thermalboard extremely close in performance.

Design Issues

  • Price: Warmboard R is approximately twice the price of Thermalboard per square foot.
  • Materials: Warmboard R uses composite OSB board. Thermalboard uses composite MDF board.
  • Tubing Spacing: Warmboard R uses a ½” tubing groove, 12” OC. Thermalboard uses a 3/8” tubing groove,8” OC.
  • Aluminum: Warmboard R uses .025” thick aluminum. Thermalboard uses .010 aluminum.
