Tacker insulation

xnet C12 tacker folding plate with a manageable 2 m² per plate. Perfect for small rooms.
Kermi x-net C12: Tackerrolle bei Verlegung
x-net C12 tacker roll in different insulation thicknesses with a coverage area up to 15 m². For use in large to medium-sized rooms.
Kermi x-net C12: Einfach zugeschnittene Passstücke
Simple cutting of fitted pieces, and minimal waste since leftover pieces are also used. Screed-separating panel connections can be made using leftover pieces without overlap using x-net adhesive tape.
Kermi x-net C12: 3 cm breit überlappender Folienüberstand der Ankergewebefolie
When using cement screed, it is sufficient to use the 3 cm wide overlap of the anchor woven foil. No gluing required.
Kermi x-net C12: Auf Dämmung aufkaschierte Ankergewebefolie
The anchor woven foil covering the entire surface of the insulation is made up of highly tear-resistant band fabric with PE overlay, including printed 5.5 cm installation grid.
Kermi x-net C12: Rohranker mit hoher Haltekraft und abgerundeter Außenkontur
The x-net C12 pipe anchor is impressive with its high retention strength and rounded external contour for effectively deflecting external forces. Six flexible barbs per pipe anchor expand under the film and form a large support surface. This reliably prevents the pipe anchor from being pulled out. The optimal interlocking of the pipe anchors under the film ensures that pipes are held securely close to the surface.

x-net 5-layer-PE-Xc tube

Kermi x-net C12: Rohraufdruck mit Angabe von Restlänge und bereits verbrauchter Rohrlänge
Printed marks on the pipe indicate the remaining length and length already used, allowing optimal utilisation of pipe coils.
Kermi x-net C12: Hohe Flexibilität bei Rohrbiegung
High flexibility allows tight bending radii and reduces the restoring forces in pipe elbows.
Kermi x-net Rohr und Rohrverbinder
Pipes and pipe connectors as defined in DIN 4726 and DIN EN ISO 15875 are tested and monitored regularly by an accredited independent testing institute.

Detail solutions - movement joint profile 10/100

Kermi x-net C12: Ausschnitt der Rohrdurchgänge mit x-net Ausklinkzange
Pipe passages cut out with x-net notching pliers. Simple cut-out positioning thanks to printed grid markings in the grid dimension of the x-net C12 tacker insulation.
Kermi x-net C12: Breiter Klebefuß und seitliche Kunststoffverstärkung
Wider adhesive foot and lateral plastic reinforcement for vertical stability and straight-line positioning.
Kermi x-net C12: kreuzende Rohrleitungen mit dem x-net Rohrschutzklebestreifen umhüllt
To allow the necessary freedom of movement, crossed pipes are wrapped with x-net adhesive pipe protection strips.

Detail solutions - x-net tacker tool

Kermi x-net C12: schmaler, abgerundeter Auflagefuß des x-net Tackergerätes
The narrow, rounded supporting foot of the x-net tacker tool enables easy and secure setting of the pipe anchor on the tacker insulation.
Kermi x-net C12: Transparente Revisionsklappe am Ausschubschacht
The transparent inspection flap on the discharge shaft can be easily opened by hand.
Kermi x-net C12: 6 Widerhaken des Rohrankers für optimalen, oberflächennahen Halt
The six barbs of the pipe anchor ensure optimal pipe retention near the surface on the tacker insulation. There are therefore only a millimetres room for movement, even under tensile load.

Detail solutions - x-net edge insulating strips H 160 mm

Kermi x-net C11: Klebestreifen zur Wandfixierung des x-net Randdämmstreifens H 160 mm
Adhesive strip for wall-fixing of x-net edge insulation strip H 160 mm. Height adjusted to the floor structure so that there is no adhesive residue visible in the wall area afterwards.
Kermi x-net C12: Folienlappen des x-net Randdämmstreifens H 160
The film lug on x-net edge insulating strip H 160 provides optimal sealing on the level tacker insulation.
Kermi x-net C11: Mehrfach-Abreiß-Schlitzung
Multiple tear-off slits for fast tool-free cutting of the edge insulation strip without leaving marks on the wall plaster.

x-link connection fitting

The combination of a bathroom radiator and underfloor heating is becoming increasingly popular. What was missing was a visually and technically convincing solution for the connection problem.

Using the x-link connection fitting, it is quick and easy to connect the underfloor heating circuit via the bathroom radiator to the existing radiator network.
