The PVC-U window system with clip-on aluminium cladding and functional aluminium profile combines the advantages of both materials in the one structural element. On the outside, the aluminium cladding offers almost limitless possibilities in colour design, whilst on the inside PVC-U profiles ensure low maintenance, high dimensional stability, and reliable functionality.
On AluClip Pro, the aluminium profile is bonded to the PVC-U profile. The aluminium then takes over the load bearing properties, and the window sash no longer needs internal steel reinforcement. This also serves to enhance the inherently good thermal insulation properties.
The KÖMMERLING 76 centre seal system offers all the benefits modern windows can give you. This centre seal system with six chambers and 76 mm construction depth offers a fascinating combination of modern design and perfect profile proportions. 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 centre 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.
The system fulfills the low energy house requirements – Uf value = 1.1 W/(m²K).
The reinforcing chambers in the sash and frame can be foam-filled on the proEnergyTec variant – Uf value = 0.82 W(m²K). This technology achieves the highest thermal insulation values and can be recycled easily at a later date.
The intelligent overall design boosts thermal and sound insulation, meaning for you greater living quality, cost effectiveness, and security.
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.
