IndorTec® THERM-W impresses with its low construction height of just 28 mm including insulation. The dry construction system guarantees quick heating of the covering, since there is no need to heat thick screed. A universal heating element for the entire pipeline ensures that installation is quick and easy.


  • Dry construction system without screed
    – Extremely quick laying, no waiting for drying, significantly reduced weight.
  • Universal heating element
    – One heating element for the entire pipeline simplifies processing
  • From a system height of just 28 mm
    ideal for renovations.
  • Uniform covering heating
    thanks to factory-installed aluminium lamination
  • Quick to react and energy saving,
    because there is no need to heat thick layers of screed.
  • Optimum use of modern heating technology and reusable energy forms such as heat pumps or solar technology
    due to low flow temperature/effective heating performance.
  • Outstanding comfort due to insulating, pressure-stable XPS with 400 kPa and improved footfall noise characteristics.
