DITRA-HEAT-TB provides a thermal break that reduces the warm-up time of your floor, especially over concrete.

Cables easily snap into place wherever heat is desired, without creating height differences in the floor.
Plus, self-leveler is not required to encapsulate the cables, which significantly reduces installation time and effort.

  1 Spool of DITRA-HEAT Cable (DHEHK12021) - Warms 21 sq ft
  1 DHERT102/BW Programmable Thermostat (touchscreen)
  2 Sensor Wires - one in each the thermostat & heating cable box
  4 DITRA-HEAT-TB Uncoupling Membrane Sheets - Covers 34.4 sq ft
