Perfect when floor height isn't a challenge

ThermoSphere Screed Cable is a versatile electric underfloor heating system which is designed for installation within the screed layer of new build or renovation projects where floor height is not an issue. Ideal for rooms that are in almost constant use as they have longer heat up and cool down times.

Economical heating

In-screed electric underfloor heating systems provide a great opportunity to take advantage of low cost energy tariffs like Economy 7 because of the slower heat up and cool down time. So, just turn it on overnight and enjoy the next day.

Screed protection

For the perfect combination, we recommend installing perimeter foam. It allows the screed to expand and contract when heated. Not allowing for this expansion could result in a breakage in the screed.
