Tradition is fine. Succes is even better. Nestle Fenster has both. Review: In 1597 Ulrich Nestle was born. He went into business for himself in 1622. Today, with Jürgen Nestle, the eleventh generation is active with the same company name and in the same sector. At that time classic handicraft – lead glazing, stained church windows etc. – played a decisive role, these days good product ideas, superior quality and intelligent technical equipment are crucial.
With his take over of the management (1990), Jürgen Nestle set the course: already with the first stage of the new construction of the plant (1993), an innovative corporate strategy had its beginning. Optimized workflows, modern management, a well-defined range of products. With the second stage of constructions (1996/97), the production area was enlarged to 2.000 m². On the new upper floor of this modern glass structure plenty of space for exhibition, consultation and administration was left.
By renting an additional production hall in 1997, the production area was enlarged to 2.300 m².
At the beginning of 2000 the production of wood- & wood-aluminium windows as well as doors went over to the utilization of a Homag CNC-machine.
The 4. stage of amelioration was conducted in 2004 in form of a new stock depot.
In 2006 again, the 5th stage was conducted. Plastic proceeding was displaced to Salzstetten and production area rose to 4.000 m².
Currently 35 people are employed at Nestle Fenster.

Our company Solmaz Machinery has been founded in 1990 with technical background, belief in producing the best and devotion of two close friends. In a short while the company has gained a significant place within the sector in machining and moulding thanks to its consistent way of working that is based on trust and high quality.

We kept growing by establishing our serial manufacturing line in accordance with sectoral needs.

Subsequently, we supported the first balcony glazing producers of Turkey with designing their systems and sharing our long year design experience. At the same time we became the first company of Turkey to produce local glazing accessories. We are proud to inspire the very first glazing system producers and steer the glazing system sector in Turkey.

After long years of supporting our shareholders with systems’ design and accessory manufacturing, our company has introduced its own brand of glazing systems – Kupa Glazing Systems. By this, we aimed at producing perfectly running systems that don’t have the design mistakes of the current brands in the sector.

Beside these, our company is the first and only company that produces all of its glazing accessories by its own. All Kupa glazing accessories are manufactured in our premises with high technology machinery by our experienced employees. By this, we guarantee sustainable quality in all of our products.
