The panels are mounted with anchors and clips on the back so that the materiality of the surface of fibre cement panels can be fully appreciated from the front without visible rivets or screws. A perfect solution from an aesthetic point of view.

Sigma—the invisible facade fastening from Swisspearl

Sigma 8 Pro

The Sigma 8 Pro is a specially developed and optimized system for the invisible fastening of facade panels. Sigma 8 Pro enables rear-fastening of 8-mm thick fibre cement panels to wooden and metal substructures for a striking and elegant look. Sigma 8 Pro can be used for the Largo and Linearis formats and for large-format panels, offering selectable panel widths and lengths up to a maximum size of 3050 x 1250 mm, and a panel thickness of 8 mm.


  • The meticulously designed front face is visible in its full splendor, especially with structured surfaces such as the Vintago and Gravial lines
  • Intuitive installation of threaded dowels and clasps
  • Optimized for durability

Sigma 12

The concealed Sigma 12 panel mount is available for a panel thickness of 12 mm. The panels are delivered cut to size and include the anchor points on the backside of the panel. The aluminum components are attached to the panels on the construction site and hung on the corresponding substructure brackets. The substructure consists either of wooden slats covered with an EPDM layer, for protection against humidity, or a metal structure made of aluminum or galvanized steel.


Developed in close cooperation with Fischer, Swisspearl fibre cement panels with a panel thickness of 8 mm can be invisibly fixed with 5-mm Fischer FZP II T-PA undercut anchors. This installation is subject to strict guidelines and must be carried out under the supervision of a local, certified Fischer partner.

Invisible facade fastening with adhesive

Panels ordered for adhesion are referred to as ARSBs. These are available upon request at the time of ordering. Standard Swisspearl panels cannot be used for adhesive application.
