Global Reach with that Personal Touch
Although we provide a global service, we strongly believe that the personal touch is central to success. To do this, we have retained the flexibility of a small company. All of our products are individually designed and manufactured in our production facility in Luxembourg, right in the heart of Europe. The assembly is carried out by our exclusive network of trained and qualified partners on multiple continents.
The dedicated Keller minimal windows® product team is committed to understanding both your requirements and your vision. We always deliver bespoke solutions, perfectly aligned to your projects and the markets you serve.
