Installation of S-Dome System
9 | 20
IN GENERAL:
¬ K2 components made of stainless steels are available in different corrosion resistance classes. Each structure
or component must be carefully checked for possible corrosion exposure.
¬ The General Installation Instructions must be adhered to.

¬ This system can be used on all established flat roof constructions with a pressure resistant substrate and a
roof pitch of up to 5°. External influences that act on this system are only reflected in the design of the bal-
last to a limited degree. For instance, unevenness, thermal elongation, moss, water accumulation and ageing
of the sheeting cannot be considered, although these factors might also precipitate system displacement
under certain circumstances. We recommend you check whether the system requires additional mechanical
attachment, as the impact of these influences may be greater on slanted roofs. The inclination of the Dome
systems is 10°.
¬ Any structural-physical aspects are to be observed. In case of any doubts an expert adviser (i.e. structural
engineer) must be consulted.
¬ Prior to placing down the SpeedRail as a base rail, a protection layer shall be used between the roof covering
and the rail to avoid any damages to the roof covering. Place the Speedrail onto the protection layer without
penetrating the roof. The compatibility of the protection layer with the respective roof covering has to be
checked by the installer. The protection layer is not part of a part of the mounting system, but is strongly
recommended.
¬ The mounting rails and the protection mats/layer shall be clean and dry before installing.
¬ The roof covering shall be clean and level. If necessary any unevenness has to be levelled out or removed.
¬ The minimum distance to roof edges is 500 mm and 300 mm to all other obstructions (i.e. skylights, vents
or similar).
¬ At least 1 row of 3 modules must be installed consecutively in order to use this system.
¬
The module distance according to the planning specifications of K2 Systems must be adhered to.
¬
The K2 S-Dome System is suitable for modules with a frame height of 30 - 50 mm.
This system is not suitable for thin-film modules.
¬
Modules with widths between 1550 - 1700 mm and a width between 950 - 1100 mm can be used.
¬ Ensure a thermal separation (distance between module blocks) after a maximum of 13.50 m in the module
row direction and in the direction of the base rail. Thermal separation can be connected using the dome
block connector in order to increase ballast effectiveness. Separation distance: in the rail direction min. 50
mm max. 80 mm. If no block connector is installed: max. 500 mm. Recommendation: min. 180 mm in mo-
dule row direction for trouble-free installation of ballast adapter.
Please note: Additional ballast is required for separation distances exceeding 500 mm. In addition, the flow
of rainwater must not be hindered.
¬ It is essential to clarify, from the start, whether there is a module manufacturer‘s approval available for the
clamping on the short side of the installation system S- Dome S1000. You can obtain the approval list from
your customer consultant or at www.k2-systems.com.
