The Kömmerling 76 centre seal AddOn system is based on the proven composite sash principle and has been further developed to integrate additional functions into the window structure in a compact design.
A key component is the optional privacy and sun protection, which is securely installed between two glass panes. This means it is not exposed to the elements and remains fully functional over time without requiring external cleaning or additional protection.
Thanks to the integrated additional glass layer, the window can reduce heat loss while also better dampening outside noise. This contributes to a quieter and more consistent indoor climate.
The system is suitable for both new construction and renovations where existing windows are to be replaced with functionally enhanced solutions.
The overall design has been revised and simplified. This results in a robust and clearly structured solution designed for long-term, reliable performance. At the same time, the system remains flexible and can be combined with other components, such as aluminum cladding systems like AluClip Plus, enabling a variety of design options.
- Privacy and sun protection enclosed between the glass panes
- No direct exposure to the elements or dirt
- Retrofittable – suitable for renovation and modernization
- Space for an integrated blind in the space between the panes
- Can reduce heat loss and improve sound insulation
- Also suitable for large window areas
- Flexible design thanks to aluminum cladding (various colors and finishes)
- Compact construction with a reduced number of components
