  • Timber floor board.


Energy savings and a fast heat-up

  1. The heat-up time for T2QuickNet, T2Blue, and CeraPro is three times faster in combination with Isolecta insulation board. This results in energy savings  of up to 65% during the heat-up phase.
  2. Approximately 20% of extra energy savings during operation due to reduced downward heat loss.
  3. The ideal substrate for tiling due to the double sided cement layer with integrated glass fiber mesh.
