FiberThermics® Technology

FiberThermics® is a registered trademark of patented ThermoSoft heating technology. FiberThermics® heating elements conduct heat through their ultra-flexible, electroconductive filaments the same way fiber optics conducts light through fibers.

FiberThermics® is the only heating system which provides an inherent Thermal Cut Off (TCO) for overheat protection across the entire length of the heating element. Therefore, self-fusing FiberThermics® offers major safety advantages over traditional metal heating wires and carbon heaters which are prone to overheat and create fire hazards.

Tailored Applications

There is no one-size-fits-all solution to every project, just like there is no single heating method appropriate for all floor coverings. That is why ThermoSoft continuously develops advanced new technologies for simple installations, tailored for all kinds of projects.

While working with the National Wood Flooring Association’s Radiant Heat Task Force, WarmStep® was established as a Fabric Heating Mat with Thermal Cut-Off . WarmStep® powered by FiberThermics® has become the most tested and approved in-floor heating system for wood, laminate and SPC Click.

ThermoSoft strives to create better, safer, and more user-friendly heating systems that are the best suited in the industry for any project.


ThermoSoft FiberThermics® technology is patented and patent pending in the USA, Canada and Mexico. In addition, Patent Cooperation Treaty (PCT) Applications are pending in countries worldwide.

ThermoSoft patents are part of comprehensive and exclusive know-how which involves constant research and development of cutting-edge FiberThermics® heating technology and fully integrated heating product manufacturing.
