The NEW heating cable that makes installation easier and faster

'In-line joint' heating cable that fits all decoupling membrane mats.

One-step hassle-free cable installation

ThermoSphere’s new Membrane Heating Cable is manufactured without bulky cold tail joints. One thickness from end-to-end also makes installation a one-step process: press in and you’re done.


Speed up installation and reduce risk

Unlike most electric heating cables, there's no bulky hot/cold joint that needs cutting into the floor. This transforms installation into a one-step process, making it faster and easier while significantly reducing any chance of accidently damaging the cold tail joint during installation. No cutting also means the membrane’s waterproofing layer stays intact.
