On 23 and 24 March 2023, the "windays" trade fair will take place at the Kongresshaus Biel. The poesia group is one of the main sponsors and a long-standing exhibitor.
The trade fair literally serves as a "window to the industry", because it is the most important conference of the window and façade industry in Switzerland. During two days, the participants will gain a comprehensive insight into the topics that are currently moving the industry. In addition, this event is ideally suited to maintain and expand the network.
