Electric Loose Cable & Uncoupling Membrane
Loose-lay electric underfloor heating cable and uncoupling membrane. Bed the membrane into flexible tile adhesive, press the cable between the studs at the spacing you need, then tile straight over. Ideal for awkward and L-shaped rooms where a mat will not fit. Also in-screed cable for new floors.
Electric underfloor heating cable and uncoupling membrane
Loose electric heating cable is the flexible alternative to mats. It's laid by hand, so it can follow any room shape: around pedestals, into alcoves and across L-shaped and irregular floors where a mat would leave cold patches.
Loose cable (10W/m or 20W/m).
- Clip the cable into uncoupling membrane at the spacing you need.
- Wider spacing gives a lower output for well-insulated rooms.
- Closer spacing gives more heat for conservatories and rooms that lose heat quickly.
Uncoupling membrane.
- Bed the membrane into flexible tile adhesive.
- Press the cable between the studs, then tile straight over.
- It also isolates the tiles from movement in the subfloor, reducing the risk of cracked tiles and grout on timber floors and with large-format tiles.
In-screed cable (20W/m). For new floors, in-screed cable is laid within the screed, which stores and releases heat steadily. This suits larger areas and longer heating periods.
Every electric system needs a floor-sensing thermostat. A qualified electrician must make the final connection. Our loose cable vs mats guide explains which to choose.
