The innovative aluminium coupled sash provides perfect multiple protection in a single system. In addition to its modern design, the Kömmerling 76 AddOn edge-seal PVC window system features an additional pane which, with an integrated venetian blind, provides outstanding protection.

Protection from the sun and view ensures a sense of comfort in the room. The Venetian blind is located between two panes of glass, which protects it from the effects of the weather. Venetian blinds can be operated manually or electrically.
The advantage you get with glass on the midfield is the improved value of sound and heat protection. Heating costs and CO emissions are significantly reduced2, and the quality of your life increases.
The Kömmerling 76 AddOn edge-seal PVC window system is best suited to renovation and refurbishment. The additional aluminium coupled sash can be fitted to almost any sash with an AluClip aluminium cover. By choosing this system you will upgrade your existing windows while sparing yourself the dirt and construction noise that come with replacing joinery.
On the inside of the window, the PVC profile ensures a high safety function and easy maintenance. You can process and paint the aluminum cladding in an almost infinite selection of colors, using various processes of finishing techniques.
Our greenline principle: energy-efficient window systems, stabilizers in fresh material without the participation of lead and an intelligent recycling concept, provide an additional plus for the longevity of the profile.
