The FischerTHERM® roof element with trapezoidal profile and thermal insulation is a steel sandwich element with a surface coating. It has a CFC- and HCFC-free polyurethane rigid foam core. It offers excellent thermal insulation and air tightness and, thanks to the Fischer DUO (Energy Saver) seal, provides additional energy savings for the roof. We think this is a good thing: It’s a valuable development for a more sustainable construction sector!

1. The safety of the photovoltaic modules must be guaranteed.
2. The performance of the thermal insulation must be maintained.
3. The tolerances of the PV construction and mounting system must be taken into account.

All this has been taken into account, guaranteed and even allowed!

Indeed, industrial and commercial buildings are particularly interested in a solution with technical approval (abZ). By “Connecting Strength” we have overcome this obstacle: the load-bearing sandwich elements with a polyurethane core between two steel facings were tested by the DIbT together with the assembly system and received technical approval as a combination (Z-10.4-901). This means security and confidence for architects, installers, planners and other industry professionals – Connecting Strength, quite simply!

The thin sheet metal screw of the K2 mounting system is screwed into the outer shell of the sandwich element with a two-pitch thread and a conical tip:

The floating system allows for expansion of the module’s carrier rail with the BasicClip. This means that the floating bearing exerts little pressure on the roof covering.

Our K2 Base software calculates the length of the mounting rails, all necessary components as well as the load calculation and creates a clear report with an installation or occupancy plan.
