76 mm systems Kömmerling 76 double seal AddOn

The Kömmerling 76 double seal AddOn system is a further development of the composite sash principle. It combines a classic window with additional functions that are directly integrated into the structure.

The optional privacy and sun protection is securely housed between two panes of glass. As a result, it is not exposed to rain or dirt and generally does not require cleaning. At the same time, it remains easy to operate over the long term, as it is not exposed to the elements.

An additional pane of glass allows the window to reduce heat loss and better block out external noise. This can have a positive impact on both living comfort and energy consumption.

The system is suitable for new construction as well as for renovations where existing windows are to be replaced with functionally enhanced solutions.

The design has also been revised: individual components have been simplified or reduced, and the mounting of the hardware has been redesigned. This ensures a stable construction and can facilitate installation. It also supports consistent quality in manufacturing.

Overall, the system offers a combination of protection, functionality, and solid construction—without additional external elements.
