In October 2017, BZ Bildung-Beratung-Innovation, a company based in Leipzig, Germany, approached erfal to enquire about the possibility of designing the Trevira joint booth at the Heimtextil 2018 trade fair using privacy rail systems. This joint booth was to be the centrepiece in hall 4.2 and aimed to stimulate contract business. 16 Trevira CS customers from the home textiles and technical textile sector would each have a separate area covering a total surface area of approximately 1,300 m². Spacious meeting islands and areas for Trevira presentations were also to be integrated. Curtains that were to function both as decoration and as a partition between the areas of the individual manufacturers were to be mounted on erfal privacy rail systems.
