76 AD Passive house

  • Outstanding thermal insulation value Uf= 0.93 W / (m²K).
  • The suitability of a passive house as defined under ift guideline WA-15/2 – Uw value = 0.79 W / (m²K).
  • Elegant aluminum design for almost unlimited color schemes.
  • High stability thanks to functional aluminum profiles.
  • Highest thermal insulation values thanks to proEnergyTec technology.
  • Fully recyclable.
  • All PVC-U profiles are produced with lead-free stabilizers based on calcium and zinc.


Want to do a lot for the environment while saving costs without sacrificing convenience and design? The passive house with KÖMMERLING 76 makes it possible. When equipped with the AluClip Pro and proEnergyTec upgrade technologies, the modern window system shows a thermal insulation value Uf of 0.93 W / (m²K), meeting the high energy-saving requirements of passive houses. With thermal insulation glazing of 44 mm and TGI spacer – Ug = 0.6 W / (m²K) – Uw value is 0.79 W / (m²K). However, the KÖMMERLING 76 with AluClip Pro and proEnergyTec can offer much more.

KÖMMERLING 76 AluClip Pro gives you the best of both worlds: aluminum and PVC-U in one innovative system. Aluminum represents convincing elegance, the best weather resistance, high stability and a wide range of colors. In addition to functional reliability, PVC-U provides optimal thermal and sound insulation. Another advantage – the functional aluminum profile takes over the load-bearing functions, so no steel reinforcements are needed.

The armature chambers in the wing and frame are filled with proEnergyTec foam. A combination with steel wing reinforcements and proEnergyTec in the frame is also possible. This technology achieves the highest thermal insulation values ​​and can later be easily recycled. The values ​​are so good that the KÖMMERLING 76 with AluClip Pro and proEnergyTec meets the requirements of a passive house.

This system also sets an example from an environmental point of view – the KÖMMERLING brand is the first key global manufacturer to produce profiles not only with sanding grinders in a pristine PVC-U window, but also exclusively with lead-free PVC with “green” stabilizers based on calcium and zinc.
Only environmentally friendly means are used with the foam, and the foam and PVC-U can be separated cleanly from each other for recycling. This guarantees that those who use KÖMMERLING products are also working to protect the environment.
