Fenster Keller AG

"Even in times of rationalization and globalization, windows are not mass-produced products.
Quality and your satisfaction are our top priorities." Ivo Keller

Fenster Keller AG is a modern family business. Window construction is our profession. Since 1947, we have been manufacturing high-quality windows, sliding doors, and front doors made of wood and wood-metal, now in our fourth generation. Our success is based on a combination of first-class materials, solid craftsmanship, and state-of-the-art technology. Entrepreneurial courage, outstanding employees, many years of experience, and the unconditional will to always be one step ahead, not only on a technical level, have enabled us to grow successfully.
