Sustainable windows
For generations TO COME
Our sustainable wood-aluminium windows are the perfect choice for environmentally conscious homeowners.
Made of high-quality materials
The main advantage of our windows lies in the use of high-quality materials. The aluminium is virtually indestructible – even in the harshest weather conditions – and remains in pristine condition for decades. Our windows are recyclable, meaning that they make a valuable contribution to sustainability even at the end of their life cycle.

Long service life
All sorts of things can happen in the life of a house. That’s why it’s important to check carefully and invest with foresight – even when it comes to windows. Wood-aluminium windows from Zöllner combine economy and ecology with aesthetics. As versatile as you like and as exact as you need them to be. In the long term.
Production
In addition to production, wood waste and shavings are used in a modern combustion plant to heat the entire facility. In addition, we cover 30% of our total electricity requirements with a large photovoltaic system.
Materials
As a renewable raw material, wood is a key component of our windows. Aluminium requires virtually no maintenance, has an unlimited service life, is extremely weather-resistant and 97% recyclable.
Innovation
Together with Innogration, we are working on the energy self-sufficient building of the future in the “Innoliving” project. Our wood-aluminium windows play a key role in the almost 60m2 office.
Prepared for the future
Older windows can be easily retrofitted to meet the latest thermal insulation and security standards without having to completely replace the window frame. For instance we simply retrofit Zöllner windows from the 1970s instead of having to replace them. This saves resources and reduces the ecological footprint.
Sustainable, robust, stylish
Choose our sustainable wood-aluminium windows and bring style, comfort and environmental protection into your home. Let us show you their incomparable quality and experience how a window can make a lasting difference to your life.
