An innovative window system that combines countless design possibilities with the best performance parameters. A defining feature of the system is the hidden sash. The frame used means that the sash profile is concealed behind the frame profile, giving the entire facade a clean and consistent appearance.

The hidden sash perfectly embodies the ‘less is more’ principle. The absence of visible structural elements has a positive effect on the subtle appearance of the window. Its minimalist, design-led form offers extensive design possibilities while providing the same high levels of thermal and acoustic insulation as other products in this system.
