The Kömmerling 88 centre seal AddOn system is based on the composite sash principle and has been further developed to integrate additional features directly into the window. Its design is intended to combine comfort with a clean, minimalist aesthetic.
The optional privacy and sun protection is securely housed between two panes of glass. This ensures it is not exposed to the elements or dirt and remains fully functional over time. At the same time, it allows for flexible control of light and privacy.
Thanks to the additional glass layer, the window can reduce heat loss and effectively dampen outside noise. This contributes to a more consistent indoor climate and greater tranquility inside the room.
The system is suitable for both new construction and renovations where existing windows are to be replaced with functionally enhanced solutions.
The design has been revised and simplified. A reduced number of components and optimized details ensure a stable and durable construction.
As a system offering greater design flexibility, Kömmerling 88 centre seal AddOn is also suitable for more demanding requirements: triple glazing and functional glass can be used, making it possible to create larger window areas. At the same time, excellent sound insulation values can be achieved.
Depending on the model, aluminum cladding panels such as AluClip Plus are available for the design, offering a wide range of colors and finishes.
