Starting out as an old handicraft business with traditional values, we began in 1992 with the manufacture of wood windows and front doors using ISO glazing.

In the beginning, the company had 7 employees; this number increased continuously. Owing to the constant expansion of our production facilities, the company today employs about 15 people including apprentices annually, enabling us to also process large orders flexibly with a high standard of quality and on time.
