Passivhaus Certified Profile 

GENEO^® is the first fully reinforced polymer window profile system that does not rely on steel for its strength. Instead, it is composed of RAU-FIPRO™, a proprietary fiber composite material similar to those employed in aeronautic construction and racing vehicles for outstanding strength and load capacities.

RAU-FIPRO, specially developed for GENEO, affords window construction benefits that previously unimaginable. GENEO does not only provide superior structural integrity but also excels when it comes to thermal and acoustical performance.

With the GENEO design, tilt-turn, hopper and fixed configurations are possible in both circular and rectangular shapes.

*REHAU window designs are supplied through a network of selected independent fabricators and installers.  ISOTOP ensures that you get the services and expertise of a certified local company backed by the resources of a global company.
