Knob plate range

With the x-net C11, pipes can be laid straight so that they run parallel to the plate edges or diagonally.

Pipes can be laid straight in parallel with the panel edges or diagonally without the need for additional pipe fasteners.

Plates from the Kermi x-net C11 knob plate range can be easily connected thanks to the thermoforming film that overlaps at the sides.

Plates can be connected easily thanks to the thermoforming film that overlaps at the sides, ensuring a screed-tight protective covering in accordance with DIN 18560.

Butting panels connected using Kermi x-net C11 connecting strips.

Butting panels connected using x-net C11 connecting strips (available as an accessory), e.g. for using up leftover pieces.

The products from the Kermi x-net C11 knob plate range can be laid quickly thanks to the large-sized plates.

Large-sized panels for fast installation, ideal for one-person pipe laying.

Pipe remains well protected by the Kermi x-net C11 knob structure during the entire shell construction phase.

Pipe remains well protected by the knob structure during the entire shell construction phase.

The special knob indentations in the Kermi x-net C11 allow different pipe dimensions to be used.

The special knob indentations in the rugged thermoforming film allow different pipe dimensions to be used while ensuring that the pipes are firmly gripped in the knob plate.

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.
