MODERN TRADITIONAL COMPANY

Handcrafted quality
Made in Luxembourg

More than anything else, we're proud of our Luxembourgian roots. For over 50 years, our family-owned firm has been making extensively handcrafted products to meet customer's specifications and backing them up with superb service. We were first awarded the "MADE IN LUXEMBOURG" label for our high standards of traditional quality more than 20 years ago and are still entitled to use it today - for good reason.

How it all began

It all began over 50 years ago with Marcel Weber, the founder of OST Fenster in small joinery in Grevenmacher. In 1985, Romain Hilger - the previos director of OST - started work in the company as a manager, at the time with 12 colleagues. Approximately 3 years later, he and his wife purchased the joinery from Marcel Weber and founded OST-Fenster S.à r.l..

Continuous development with the corresponding investments is a must for the existence of the company and the safeguarding of jobs. This also includes the handover to the next generation in the family dynasty, which took place in 2019.
OST-Fenster S.à r.l. became OST-Fenster S.A.

It all began over 50 years ago with Marcel Weber, the founder of OST Fenster in small joinery in Grevenmacher. In 1985, Romain Hilger – the previos director of OST – started work in the company as a manager, at the time with 12 colleagues.

Approximately 3 years later, he and his wife purchased the joinery from Marcel Weber and founded OST-Fenster S.à r.l.. After purchasing a plot of land in the then-new industrial park in Potaschberg, the process of building a new production hall with office buildings and a total floor space of 3000 m² was begun.

At the beginning of 1991, 16 employees began their work in the completed building.

From mid-1997, the company had its own sales department, which has been continually expanded since then to keep improving the level of customer service.

In 1999, OST celebrated its first internet presence, in those days at the www.ost-fenster.lu domain.

In 2002 and 2003, the company invested in modern plants and machinery, and production was switched to ONLINE control.

OST became the first trade company and only the second company in Luxembourg to receive the official certificate for e-commerce in 2003.

Two years later: our new showroom in the form of a large conservatory at our headquarters in Grevenmacher was opened.

In July 2010, OST became the first foreign company to be included in the FLG. The FLG is a Window-Performance-Association (Fenster-Leistungs-Gesellschaft) that unites 19 of the most prestigious German window makers. In the same year, the neighboring building was acquired for expansion purposes.

In 2011 – after extensive rebuilding and furnishing – the service department, as well as the accounts and finance departments, moved into the new building, Manufacture II. In autumn 2011, our photovoltaic project was launched in which panels with a rated output of 250kW peak were installed on the roofs of the halls.

In 2012, besides new software and new tools, OST also invested in a highly automated production line, the Working Process Logos Team – a high-precision and flexible machine.

One year later, building work began on a connecting hall between “Manufacture I” and “Manufacture II”. This connecting hall allows a better production flow, right up to the packaging and loading of the finished products.

In 2017, we invested in a new modern painting line. A high-tech, fully automatic painting system for windows and doors. The two spraying robots and the electronic system for shape detection make it possible to paint each type of door and window with its own paint specifications in the highest quality. 

TRADITION MEETS INNOVATION

Keeping what is good
integrating the new

Our commitment to manual production doesn't mean that we completely forego modern technology. State-of-the-art equipment maximizes our flexibility for implementing the creatives ideas and special wishes of builder-owners or architects. We have a fleet of high-performance machines to facilitate our work and ensure a consistently high standard of quality. It is this blend of manual skills and innovative technology that makes our products so unique - which everyone can see and feel for many, many years.

WORKSHOPS

Genuine specialists
for the perfect finishing touch

It isn’t just the smell of wood that our workshops share with the joineries of yesteryear. It is also the people who work in them, applying enormous manual skill to create new objects from this natural raw material. There aren’t any assembly lines at OST. Instead, we have many small work centers, each of which is run by a specialist. Every stage of production – whether it is cutting to size, planning, milling, grinding or painting – is executed with extreme meticulousness and patience, quite literally all the way to the perfect finishing touch.

PLANNING

Look into the future
and keep going

To us, it’s not enough to simply deliver good products. That’s why we take the decisive step earlier in the process by offering individual consultation services right from the planning phase of your project. Our goal: to fulfill the expectations and requirements of both architects and clients, allowing the ideas and their implementation to become one perfectly harmonious unit. 
Of course, this requires a variety of criteria to be fulfilled. For example, we take care to choose the best possible quality of materials and components, implement energy-related requirements and take sound insulation and protection from break-ins into account.

To put it simply: together with you, we think ahead – right up to the custom-fit installation of your project on-site.
