WERU, a traditional German company that started out as a carpenter's workshop, is the oldest window production factory in Germany. The more than 1,000 employees of the WERU Group produce over 400,000 sashes and around 10,000 front doors every year.

Behind WERU’s success lies a history that is rich in experience, sustainable thinking and the attitude of never being satisfied with the standards achieved. WERU performs continuous quality assurance from production to installation, certified by the RAL Quality Mark. Production takes place at the three German locations in Rudersberg (Baden-Württemberg), Triptis (Thuringia) and Salmtal (Rhineland-Palatinate). 

WERU GmbH is one of Europe’s leading manufacturers of windows and front doors and can reflect back on a success story of over 175 years. WERU was founded in 1843 and the product portfolio was expanded through the merger with UNILUX GmbH in 2014, to include wood and wood-aluminium products and create a comprehensive full range.

Behind the success of the companies lies a history that is rich in experience, sustainable thinking and the attitude of never being satisfied with the standards achieved. Today, the WERU Group positions itself as a future-oriented company that demands maximum individuality. Modern windows, large lift-slide combinations, front doors in all material variants bring dynamics to the home and in doing so enrich both the façade as well as personal life.

WERU distinctly positions itself as a complete solution provider. True to the motto: Everything from a single source. With LiSEC as a long-standing business partner, the decision was made in favour of a company with the same objective. The cooperation between WERU and LiSEC began when WERU started to manufacture insulating glass. At that time (and still today), LiSEC was the only company on the market to offer complete systems, from glass cutting to logistics, including its own LiSEC software.

"Business is always conducted between people. When two strong brands come together for a joint project, this means mutual professional planning and concept design, clean implementation by both parties, and the pleasure of being successful together," says Clemens Macarei, Head of Product Management at LiSEC and point of contact for WERU for decades. 

In 2020, a new high-performance machine for automatic laminated glass cutting was put into operation: The VSL-A. Following WERU's decision to invest further in the laminated safety glass (LSG) sector, the decision was very quickly made in favour of a LiSEC system. The purchase was made directly at the trade fair. "Data, facts and figures were very important to us, in particular the issue of material savings and how the system adds up, in other words the profitability. The confidence that the machine would be a success was very high, thanks to our experience of outstanding cooperation with LiSEC in the past," says Jens Reimann.

The VSL-A combines state-of-the-art laminated glass cutting technology and decades of LiSEC know-how in automatic laminated glass processing. Depending on the optimisation, up to 30 % higher cutting capacities are possible. Automatic rotation of the sub-plates is part of the standard equipment, as is automatic residual cut disposal, and reduces operator intervention to a minimum. In addition, two cutting heads ensure an automatic tool change. 

The topic of sustainability is very important to WERU. The traditional company focuses on sustainable production and material processes, as well as smart, future-oriented products. Not only when it comes to glass, but across the entire production process. The VSL-A supports this by reducing glass consumption. On average, 6 % glass consumption can be saved by the VSL-A.

"Our cooperation with WERU is characterised by a strong sense of partnership. Both companies benefit from the advantages of the other and further develop together," says Markus Ensafi, LiSEC Sales Manager.
