Innovations and advantages versus a heating mat

LARX Carbon Kit LARX Carbon Kit
Heating mat Heating mat

Whole surface heating

Compared to LARX Carbon Kit, which emits heat by its whole surface, a heating cable or mat is only a linear heating element. Therefore, the temperature distribution in a floor is never as good as is using our Carbon Film (even if the meander of a heating cable or mat is perfectly laid).

Savings due to effective heat transfer

LARX Carbon Kit has a contact with flooring by its whole surface. Thanks to this the temperature distribution and heat transfer is much more effective, compared to a heating cable

Full function even when pierced

Unlike linear systems (meander) the Carbon Film is working even if it is accidentally pierced.

Application under screed or under flooring

Thanks to simple and exceptionally thin structure LARX Carbon Kit can be installed both under screed and directly under floating flooring with a click system (certified for underfloor heating).
