Press Release: Optiwin Successfully Completes Quality Audit for Major Project

Optiwin has once again demonstrated its leading position in wooden window construction. As part of a large-scale project for Strabag AG, one of Austria’s top construction companies, the company successfully passed the quality audit conducted by PfB GmbH & Co. Prüfzentrum für Bauelemente KG, a company of the TÜV NORD GROUP.

Innovative Achievement with Exceptional Precision

At the center of the audit was a panoramic sliding door with a fixed part that can be installed completely frameless. This construction impresses not only with its dimensions – 6.70 meters in width and 3.54 meters in height – but also with outstanding results in air permeability and water tightness tests. Achieving top-tier classifications, the sliding door delivered exceptional results, particularly for an element of this size. For example, it was tested and passed in extreme classes for water tightness.

“The challenge of achieving good results with lift-and-slide doors increases proportionally with the size of the element. That’s why we are especially proud that we not only met but exceeded our targets with our constructive and static design,” commented Jakob Astner, Managing Director of Optiwin.

Optimizations and Insights for the Future

During the audit, not only were the high requirements met, but additional optimizations were made to the design. The results highlight that the combination of innovation and experience at Optiwin leads to extraordinary products.
