The NEW heating cable that makes installation easier and faster
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.

Use it with any membrane mat
ThermoSphere’s Membrane Heating Cable is compatible with all decoupling membrane mats. This means you can use your preferred brand of decoupling mat with the easiest to install and most reliable heating cable.

Take advantage of in-line joint and TwistedTwin technology
ThermoSphere’s Membrane Heating Cable is the ONLY heating cable to combine in-line joint technology with TwistedTwin cable construction. This makes it the most robust 'in-line joint' heating cable you can use – giving quick quality workmanship for your customers.

A cable for every project
We've introduced four new cable sizes into the ThermoSphere Membrane Heating Cable range. You can choose from a wider range of cable sizes: 42m, 55m, 90m and 175m. These new sizes give installers more options to ensure they can install the perfect heated area without needing to use multiple cables.

What is ThermoSphere’s Membrane Heating Cable?Our in-line joint membrane cables do not have bulky hot/cold joints that are created after the primary manufacturing process. They are the same thickness from the end termination to the cold tail that connects to the thermostat. This makes them stronger, more reliable, and easier to install.
-
Why are ThermoSphere’s Membrane Heating Cables better?
Our in-line joint membrane cables make installation easier because installers don’t have to cut into the membrane, insulation board, or chase out concrete. Cutting and chasing also makes joints the most common point of failure during installation. Removing the bulky joint removes that risk too.
-
How easy is it to install ThermoSphere’s Membrane Heating Cable?
Very. You can simply press the cable into the membrane mat, covering the whole of the heated area, and you’re done. Because there are no bulky joints or thicker cold tail cables, installation is a one-step process. The membrane and cable are automatically flush and ready for tiling.
-
What cable lengths are available?
There are four new cable lengths: 42m, 55m, 90m and 175m. But all the existing lengths will become in-line joint too, which means you’ll have a cable for every project.
-
How much more do I need to quote for jobs with new ThermoSphere Membrane Heating Cables?
It’s the same price, but better cable, so nothing needs to change with the way you work. The only difference is the new product codes have “J” on the end – oh and installation is much easier too, so you’ll spend less time on site.
