1Application directly
under floating flooring

Acoustic insulation LARX CARBON-FILM.COM PE film 0.2 mm Laminate flooring
  • 1Any flooring with click system
  • 2PE film 0.2 mm
  • 3LARX Resilient Carbon Film
  • 4Acoustic insulation

Simple description of the application directly under floating flooring (see more in the full manual)

  1. On a cleared floor without unevenness place an acoustic insulation. It serves also as a thermal insulation. The LARX Resilient Carbon Film’s power cables are laid into grooves in this acoustic insulation.
  2. According to the project measure and cut strips of LARX Resilient Carbon Film.
  3. Lay LARX Resilient Carbon Film in the designated place and fix it against displacement.
  4. By the clamp plier press the connectors to the film. Exact positioning is important – the connector must be in place of the copper strip inside the film.
  5. Measure the electrical resistance according to the Warranty certificate.
  6. Strip the power cables by a wire stripper. For the first strip of LARX Resilient Carbon Film remove the insulation on the end of the cable. In the case of next strips, remove the insulation continuously. Press the cable into the connector by the clamp plier.
  7. With two butyl tapes insulate the cut and the connectors. Insulate the other end of the strip with one butyl tape folded in half.
  8. Prepare grooves in the acoustic insulation and lay into them the power cables and eventually the insulated ends of LARX Resilient Carbon Film.
  9. A professional person with the electrician certificate connects LARX Resilient Carbon Film inside a wiring box or a thermostat.
  10. In the case of more LARX Resilient Carbon Film strips in one room it is possible to connect them in series or in parallel.
  11. For a floor heating it is necessary to place a temperature sensor into a groove in the acoustic insulation (directly under LARX Resilient Carbon Film) and fix it against displacement.
  12. Cover all LARX Resilient Carbon Film strips with a protective PE film.
  13. Measure the electrical resistance according to the Warranty certificate and draw the position of every LARX Resilient Carbon Film strip, cable, connection and device.
  14. Check everything and lay flooring with click system according to instructions of the manufacturer.

2Application
under screed

LARX Resilient Carbon Film PE film 0.2 mm Anhydrite / concrete Possible tile glue Any flooring / tiles
  • 1Any flooring / tiles
  • 2Possible tile glue
  • 3Anhydrite / concrete
  • 4PE film 0.2 mm
  • 5LARX Resilient Carbon Film

Simple description of the application under screed (see more in the full manual)

  1. LARX Resilient Carbon Film is usually laid on a thermal insulation (polystyrene).
  2. According to the project measure and cut strips of LARX Resilient Carbon Film.
  3. Lay LARX Resilient Carbon Film in the designated place and fix it against displacement.
  4. By the clamp plier press the connectors to the film. Exact positioning is important – the connector must be in place of the copper strip inside the film.
  5. Measure the electrical resistance according to the Warranty certificate.
  6. Strip the power cables by a wire stripper. For the first strip of LARX Resilient Carbon Film remove the insulation on the end of the cable. In the case of next strips, remove the insulation continuously (see picture). Press the cable into the connector by the clamp plier.
  7. With two butyl tapes insulate the cut and the connectors. Insulate the other end of the strip with one butyl tape folded in half.
  8. A professional person with the electrician certificate connects LARX Resilient Carbon Film inside a wiring box or a thermostat.
  9. In the case of more LARX Resilient Carbon Film strips in one room it is possible to connect them in series or in parallel.
  10. Cover all LARX Resilient Carbon Film strips with a protective PE film.
  11. For a floor heating it is necessary to place a temperature sensor on the PE film directly above LARX Resilient Carbon Film and fix it against displacement.
  12. In bathrooms, LARX Resilient Carbon Film must be fully covered by a grounding net. This grounding net must fulfil the local standards and must be grounded (PE).
  13. Measure the electrical resistance according to the Warranty certificate and draw the position of every LARX Resilient Carbon Film strip, cable, connection and device.
  14. Check everything and pour the screed according to its manufacturer’s technological procedure. The minimum thickness of anhydrite or concrete above LARX Resilient Carbon Film is 45 mm.
