flat rail

roof-parallel installation up to 20° of rooftop angle
for foil, bitumen and concrete

schnelle Montage

fast mounting

entwickelt im Windkanal

developed in a wind tunnel

Ultraleicht und nahezu ballastierungsfrei

ultra lightweight with a minimum of ballast needed

Flexible system for various application fields

Our roof-parallel system flat rail features perfect simplicity being suitable for bitumen, foil or concrete rooftops up to an inclintation angle of 20°. The system is to be mounted with only one tool within record time of 10 to 15 kWp per man-hour – already including the modules. For ballasting we offer system-compatible ballast trays to be mounted beside the modules.

Due to its short and space-saving dimensions the mounting system easily skirts obstacles like rooflight domes, giving you flexible scopes of application on site.

“We´ve already installed numerous mounting systems being able to say that yours is the fastest and most comfortable one by far.”

– Ricardo Latzkow,
Head of project management, Polarys

Advantages for you:

  • developed and aerodynamically optimised in a wind tunnel
  • suitable for roofs with a limited load-bearing capacity
  • fully optimised prefabrication
  • flat rail is resistant to UV, wind and corrosion
  • quick installation saves time and money: no other mounting system on the market can be installed faster
  • minimum shipping and storage costs thanks to the small scale of the product: up to 50 kWp of flat rail measure 2 x 1.25 metre in packaging
  • rooftop impermeability is not affected by our prduct in any case, thanks to the integrated building protection mats
  • multi-directional water drainage guaranteed
