System with three sealing levels. Internal, middle and outer permanently elastic seals provide permanently elastic sealing between the wing and the frame.

Whether function, structural properties, insulation values, environmental protection, or preservation of value, it fulfills the requirements of both today, and above all tomorrow. The KÖMMERLING 76 double seal system is such an innovative design that it can take modern triple glazing or special functional glazing with panes up to 50 mm thick. Thanks to intelligent fastening technology, the professional installation is fast, clean, and effortless. So replacing old windows with new modern KÖMMERLING 76 double seal systems could not be easier.

Even the standard system version fulfills the low energy house requirements – Uf value = 1.1 W(m²K). The intelligent overall design boosts thermal and sound insulation, and you profit from greater living quality, cost effectiveness, and security.

Combine form and colour just as you wish. An extensive profile range – with offset, semi offset, and design sash – and various surface finishes offer a great many possibilities. The system is available in white, woodgrain laminates, or plain or metallic colours – laminated on the outside and white on the inside, or laminated on both sides. Moreover, KÖMMERLING 76 is available with the new innovative surface technology proCoverTec in a further 26 colours.

This system also sets an example from the ecological viewpoint – The KÖMMERLING brand was the first key producer in the world to manufacture profiles not only with regrinds in virgin window PVC-U, but also exclusively with lead-free PVC with “green” stabilisers based on calcium and zinc. This guarantees that those who use KÖMMERLING products are also working to protect the environment. ​
