The wide selection of sizes means installation is simple and can be done by the customer themselves or the floor layer. One kit contains one strip of carbon heating Film of a specific size.

  • Maintenance-free comfortable system
  • No limited functionality when drilled through
  • Use as a main and additional heat source

Innovative compared to heating mats

Area-wide heating

LARX Carbon Kit really heats the whole area. A heating cable or heating mat is only a linear heating element. Therefore, even with the best arrangement of the heating cable or mat, the temperature distribution in the floor will never be as good as with the LARX Carbon Kit.

Savings due to more efficient heat transfer

LARX Carbon Kit has contact with the entire area of the floor covering. As a result, temperature distribution and heat transfer are much more efficient than with a heating cable.

It still heats when drilled through.

Unlike line systems (snake), carbon heating Film will still work and heat without any problems even if it is accidentally drilled through.

Into screed and directly under the floor covering

Thanks to the simple and exceptionally thin construction, the LARX Carbon Kit can be placed not only under the screed, but also directly under interlocked floor coverings (suitable for electric underfloor heating).
