The interest was great and the discussions animated: The airdome day of HP Gasser AG in Wohlen was a complete success. Around 30 people took a close look at the new panorama hall of the TC Wohlen on March 22 – an innovative construction from HP Gasser. It captivates by the built-in window row made of transparent ETFE foil. This does not change the characteristics of an airdome, but it does open up new views and vistas for spectators and indoor athletes. Our membrane construction specialists provided all the necessary information on site. This also included tips and tricks for reducing the operating costs of airdomes. The visitors were particularly interested in the modern heating/ventilation system, which can be controlled remotely. During lunch and later at afternoon coffee, there was enough time to answer individual questions and to exchange ideas.
