Bydgoszcz Fair & Exhibition Centre

The Bydgoszcz Fair & Exhibition Centre opened in 2012, to instantly become a business landmark in the Kujawsko-Pomorskie Province.

Most of the building outer walls were constructed based on Balex Metal 18-cm standard mineral wool core sandwich panels. The panels were chosen because of the high sound-proofing requirements related to this project.
