There were no significant differences in test results during this Round Robin with the labs using Kaowool vs. other refractory board. There were no significant differences in test results during this Round Robin with the labs using Kaowool vs. other refractory board. Labs using an Electric Radiant Panel that are experiencing higher than average stabilization times should check their controller settings for their mode of operation. Labs using an Electric Radiant Panel that are experiencing higher than average stabilization times should check their controller settings for their mode of operation. Non-Participating Labs will be included in future Round Robins. Non-Participating Labs will be included in future Round Robins.
