BAU is an important trend setter for the industry. This was the reason why HIRT decided to showcase the descending wall to a discerning international audience at BAU Munich 2017 at their two-story stand. The success proved this decision right. The unique way in which HIRT Swiss Descending Windows opens up spaces was made tangible with an impressive live presentation in the exhibition hall. Renowned architects came to get first-hand information on which dimensions and materials can be specified with our descending walls. Delegations of HIRT partners from Australia and the United Arab Emirates visited the stand. Builders stopped by to let themselves be inspired. For Stefan Hirt, talks with potential sales partners in other countries, including Israel and Brazil, also greatly contributed to making this event a big success. The five colleagues staffing the HIRT Swiss Descending Windows stand were able to gain numerous new contacts, several of which made concrete project inquiries. One deal was even closed live: Gerhard Gerstenmayer, the Official Sales Partner in Germany, and the representative of Medicke Metallbau signed the contract for a project in Berlin.
