Invisible Mechanical Fixing System (Keil System)

In this system, brackets and anchors are installed behind the ceramic tiles and placed on the aluminum substrate on the building facade. The brackets are made of aluminum. It is easily possible to adjust or replace any of the ceramic tiles anywhere on the façade.

Preparation of ceramic panels

Preparing a ceramic panel involves the following steps:


After these steps, the ceramic panel is ready to be fixed on profiles.

Undercut hole geometry

  1. Preparing a workshop plan based on the current condition of the building façade
  2. If necessary, the installation of a steel substructure to eliminate dimensional irregularities in the building
  3. After designing the facade elements, according to the obtained design, the brackets are connected to the retaining wall or steel substructure by mechanical fasteners.
  4. At this stage, suitable thermal insulation is applied to the retaining wall.
  5. Considering the issue of civil defense and to prevent the ceramic tiles from falling from the facade, all the ceramic tiles should be reinforced with fiberglass mesh and suitable adhesive.
  6. Ceramic back holes are made using a special drilling machine and drill head.
  7. The anchors are placed inside the undercut holes and the brackets are screwed. (To ensure a sturdy connection, the holes are filled with flexible polyurethane adhesive)
  8. After that, the vertical profiles are connected on the brackets at a distance of approximately 15 cm from the facade of the building.
  9. Horizontal profiles (runners) are also installed on vertical profiles at appropriate heights.
  1. The ceramic panels are placed on the substructure by hanging the brackets behind the panel to the runners.
  2. Finally, to obtain a suitable horizontal joint, the panel is placed in its proper place by an adjusting screw.
  3. The facade is created by repeating this process.

It is recommended that the vertical profiles be cut at the floor levels so that each part has a separate function from the other parts.
