"Even in times of rationalization and globalization, windows are not mass-produced products.
Quality and your satisfaction are our priority." Ivo Keller
Our windows are still manufactured in traditional individual production - supported by state-of-the-art technology and an infrastructure that leaves nothing to be desired in terms of quality assurance. We would be pleased to take you on a "tour" and show you how we create a tailor-made quality window from wood, glass and metal.
