The ThermoSphere Ultimate Heating Cable offers a quick and hassle-free installation, making it the most reliable choice for underfloor heating. Featuring innovative TwistedTwin cable and in-line joint technology, it eliminates the need for cutting into the membrane or substrate, reducing the risk of installation damage. Compatible with all decoupling membrane mats, ThermoSphere Ultimate lets you pair it with your preferred matting brand while enjoying a dependable and easy-to-install heating solution.

Features & Benefits:

  • There is no bulky hot/cold joint that needs cutting into the floor - Installation is quick and easy.
  • Install ThermoSphere Ultimate into ThermoSphere Membrane or Self-adhesive Membrane at either 130W/m² or 195W/m2.
  • ThermoSphere Membrane’s decoupling properties neutralise lateral movement in the floor and minimise the risk of cracking and delamination.
  • Creates a waterproof layer within the floor when used with waterproofing products.
  • Fleece backed membrane is adhered with a flexible tile adhesive, and self-adhesive membrane can be laid directly onto a clean plywood sub floor
