x-net® C15 thin layer system

Underfloor heating especially for renovations with a thickness of just one centimetre that still packs a punch!

Kermi x-net C15 thin layer system – underfloor heating with a thickness of just one centimetre that still packs a punch, specifically intended for renovation projects.

Underfloor heating for renovation projects. Super slim, lightweight, and quick – these are the special strengths of the x-net C15 thin layer system. In contrast to conventional systems, the knob element in the x-net C15 thin layer system is designed in such a way that the sealing compound permanently bonds with the substrate, thereby enabling an extremely shallow floor structure. This makes the system ideal for efficient renovation solutions, with the option of heating and cooling. Can be laid directly on a wide variety of existing floor coverings without the need for costly chiselling or demolition work.

Advantages

x-net C15 thin layer system

Heating and cooling

  • One system, two functions

Ideal for renovations

  • Perforated knob element made of polystyrene, prevents mould formation
  • Low element height of 14 mm, complete floor structure 17–22 mm (without floor covering)
  • Short drying times
  • Low static weight
  • Can be laid without chiselling or demolishing work
  • Connection of x-net knob elements using connection technology – precise, reliable, quick and tool-free

Suitable for universal use on substrates

  • Can be applied to a large number substrates after appropriate pre-treatment
  • Self-adhesive back adheres to virtually all steel substrates

Sturdy, secure, and flexible

  • Highly impact resistant knob element
  • Composite structure is extremely stable because the knobs are completely filled with sealing compound and the connection to the substrate is established using a perforated film structure
  • High pipe retention strength thanks to optimal indentations in the thermoforming film
  • Two pipe dimensions – one knob element:
    • x-net 5-layer pipe 10 x 1.3
    • x-net 5-layer pipe 12 x 1.4

Installation distances in conformity with standards

  • System-specific, completely straight routing of pipes and pipe distances that conform to standards
  • Pipes can be laid parallel and diagonally without the need for additional pipe fasteners

Certified and sustainable

  • Heating technology tested according to DIN EN 1264 and DIN CERTCO certified
  • Free from CFCs and HBCD

Pipe dimensions

Pipe dimensions of both 10 x 1.3 mm and 12 x 1.4 mm can be laid using the same knob element. In contrast to the 10 x 1.3 mm pipe dimension, the x-net 5-layer pipe measuring 12 x 1.4 mm has a flow cross-section that is 35 % greater, thereby enabling:

  • Longer pipe lengths in the heating circuit
  • Fewer heating circuits for the same area, in turn allowing manifolds and manifold cabinets to become more compact
  • Lower material and installation costs

x-net C15 thin layer knob element

Kermi x-net C15 thin layer knob element – fixed in position by the self-adhesive backing.

Secured by the self-adhesive backing on the knob elements. Simply remove the protective film and lay on an appropriately pre-treated substrate.

The pipe inserted in the Kermi x-net C15 thin layer knob element can be fixed in any direction without the need for any additional pipe fasteners.

The pipe can be fixed in any direction without the need for any additional pipe fasteners.

Kermi x-net C15 thin layer knob elements have a special design.

The sealing compound flows through the punch-outs in the knob element. This creates a stable bond with the load-bearing substrate (which needs to be prepared according to the instructions of the sealing compound manufacturer).

x-net 5-layer PE-Xc pipe

Kermi x-net 5-layer PE-Xc pipes have marks printed on them to indicate the remaining length and pipe length already used, thereby ensuring optimal utilisation of pipe coils.

Printed marks on the pipe indicate the remaining length and pipe length already used, allowing optimal utilisation of pipe coils.

Because of their high level of flexibility, the Kermi x-net 5-layer PE-Xc pipes allow tight bending radii while ensuring low restoring forces.

The high flexibility allows tight bending radii and reduces the restoring forces in pipe bends.

Kermi x-net 5-layer PE-Xc pipes and pipe connectors tested according to DIN 4726 and DIN EN ISO 15875.

Pipes and pipe connectors according to DIN 4726 and DIN EN ISO 15875 are tested and monitored regularly by an accredited independent testing institute.
