S:FLEX insertion system with smart technical details


Perfect appearance and unrestricted functionality
Insertion rail and ELS Fix clamp

The advantages of the S:FLEX insertion system at a glance:

  • Aesthetically pleasing modular surfaces with clean finishes for pitched roofs with any type of tile covering as well as metal roofs
  • Can also be installed as a PV façade system or used on noise barrier walls and solid balustrades on balconies
  • All components for a special look also available in black
  • Suitable for module frame heights of 25 to 45 mm - using just one type of insertion rail
  • Thanks to the hollow chamber profile, the rail has a very high static load-bearing capacity for a larger span with fewer roof connection points
  • With newly developed module clamps that combine the advantages of floating installation and firm clamping: no rattling of the modules and no thermally induced glass breakage or micro-cracks
  • Aluminum spacers integrated in the module clamps make the installation and maintenance of additional rubbers et al. redundant
  • Simple grounding with optional pre-assembled grounding clips
  • Service-optimized: Modules can be loosened and removed with just a 5 mm Allen key thanks to maintenance gaps




The solution for the optically and technically demanding.

With the S:FLEX insertion system, PV systems can be implemented with module surfaces that fit harmoniously and coherently into the roof look, despite the low installation and maintenance costs. An innovative module clamp and the one-for-all insertion rail ensure that aesthetics does not mean sacrificing functionality .

Private PV system operators will primarily appreciate the looks and stability of this fastening solution, and the flexible application options are interesting for housing associations while installers will benefit from the service-friendliness and simplified system planning and warehousing.
