Fastening OmegaS with Omega profile and supporting profile

System description

Omega profile and OmegaS supporting profile permit vertical installation of the KeraTwin® facade panels. Secured to the vertical supporting structure, the OmegaS profiles arranged horizontally carry off wind loads and the dead weight of the panels is carried off by the supporting profile mounted in the height grid. The KeraTwin® K20 facade panels are simply hung horizontally in the Omega profiles using the holding grooves on the reverse side. No additional tools are required for mounting the panels. The compression spring integrated in the Omega profile prevents clattering and constraining forces in the case of alternating wind loads. Each KeraTwin® panel is secured using two securing angles to prevent it from slipping out. The horizontal joints can be open or closed with joint profiles.

Mounting instructions for KeraTwin® K20 – OmegaS with Omega and supporting profile


The mounting of the substructure must be carried out according to project-specific, static calculation. The general approval Z-10.3-844 of the construction supervisory authority serves as basis.

  • The profiles of the basic substructure have to be mounted perpendicularly and in a flush way.
  • Fix the horizontal K20 Omega profiles (Art. no. 627) at the pre-installed vertical substructure by means of the supplied fastening materials. The vertical distance depends on the panel length - single-span girder (= 1/2 of panel length), with jibs on both sides (= 1/4 of panel length).
  • Mount the supporting profiles according to the height grid (panel length + 8 mm).
  • Fully insert the KeraTwin®-panels in the construction.
  • Position the securing brackets at both Omega profiles and fix them.

Omega profiles and OmegaS supporting profile available for all standard grids. Other grids available on request.

Important: The use of silicone caoutchoucs must be absolutely avoided, because silicone fluids segregate and effect sticky surfaces on which dirt adheres. Therefore, only use the system components mentioned (foamed pieces, EDPM rubber profile, neoprene rubber washer) and pointing, bonding and sealing materials recommended by us. We will be pleased to inform you in detail. The usual final cleaning after completion of the construction works is still required. A warranty for the system KeraTwin® K20 in the scope of the general approval no. Z-10.3-844 of the construction supervisory authority only applies if the system components shown on these pages are used.
