NEW, YES, WORKING? Want to do a lot for the environment, yet save costs without sacrificing convenience and design? A passive house with KÖMMERLING 76 makes this possible. When fitted with the upgrade technologies AluClip Pro and proEnergyTec, the modern window system exhibits a thermal insulation value Uf of 0.16 BTU/(hr 0F ft2) or 0.93 W/(m²K), fulfilling the high energy saving requirements for passive houses. With 44 mm thermal insulation glazing and TGI spacer – Ug = 0.11 BTU/(hr 0F ft2) or 0.6 W/(m²K) – the Uw value is 0.14 BTU/(hr 0F ft2) or 0.79 W/(m²K). Yet KÖMMERLING 76 with AluClip Pro and proEnergyTec can offer a lot more besides.
KÖMMERLING 76 AluClip Pro gives you the best of two worlds: aluminium and PVC-U in the one innovative system. Aluminium presents a convincing elegance, the best weather resistance, high stability, and a wide range of colours. PVC-U provides the optimal thermal and sound insulation in addition to functional reliability. Yet another advantage – The functional aluminium profile takes over the load bearing functions, so no steel reinforcements are needed.
The reinforcing chambers in the sash and frame are filled with proEnergyTec foam. Also possible is the combination with sash steel reinforcement and proEnergyTec in the frame. This technology achieves the highest thermal insulation values and can be recycled easily at a later date. The values are so good that KÖMMERLING 76 with AluClip Pro and proEnergyTec fulfills passive house requirements.
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.
Foaming makes exclusive use of eco-friendly agents, and the foam and PVC-U can be separated cleanly from each other for recycling purposes. This guarantees that those who use KÖMMERLING products are also working to protect the environment.
