Higher output
Conductive paths between particles allow more current to flow. The element produces heat.

Nanotechnology and the PTC effect
The material itself adjusts the heat.
STEP® stands for Self-regulating Technology of Electro Plastics. Its heating elements are made from a polymer containing carbon nanoparticles distributed throughout the material.
They work through a positive temperature coefficient, or PTC: as the material’s temperature rises, its electrical resistance also increases. Current then decreases, reducing heating output.
Increasing resistance
Polymer expansion reduces conductive paths between particles. Current flow gradually decreases.
Output that adapts
The element reduces its heat output as it warms and increases it as it cools. The thermostat still controls the comfort setting.
Low-voltage power supply
A system designed as a whole.
STEP elements can operate on alternating current (AC) or direct current (DC), depending on the model and configuration. In a conventional installation, a transformer supplies the appropriate voltage to the heating elements.
An alternative energy source may also be considered, without an inverter in some compatible DC configurations. Voltage, available power and controls must be validated for each project.
Self-regulation complements the thermostat
The material adjusts output according to its own temperature. The thermostat controls the desired temperature and accounts for factors such as solar gains and other heat sources.
The PTC effect helps limit hot spots. Assembly design, electrical protection and compliance with the manufacturer’s instructions remain essential.
Distributed warmth
A large heat-transfer surface.
The flat elements spread heat over a broad area. STEP’s technical document states that an installation can cover more than 60% of the surface, depending on the layout. This distribution promotes an even surface temperature.
Thin and flexible
Approximately 1.2 mm thick for the product shown, the film fits into various assemblies in new construction or renovation.
Adaptable to the project
Elements are supplied in rolls of different widths. On-site cutting and connection must follow the product-specific limits and instructions.
Appropriate thermal design
Insulation, heat loss, coverage and flooring together determine comfort and energy requirements.
02 / Output over time
Output decreases as the element warms.
Understanding consumption
As the element warms, its electrical output decreases. The manufacturer’s document illustrates this with an initial output of 4.5 W/ft², potentially dropping to about 3 W/ft² under the described conditions. These values illustrate operation and are neither a sizing specification nor a consumption guarantee for your building.
For the same electrical energy consumed, resistance heating systems produce comparable amounts of heat. Actual consumption mainly depends on building demand, insulation, controls and operating conditions.
Indoors and outdoors
One technology, multiple applications.
Radiant floors
Primary heating where heat-loss calculations allow, supplemental heating or simply warming the floor. Various assemblies can accommodate wood, laminate, carpet, stone or tile, subject to compatibility and temperature limits.
