Cloud Lounge’s roof

Bregenz (A) 2015

The Casino’s new roofing for the summer terrace “Cloud Lounge” in Bregenz is a perfect scenery for all sorts of events.

A cloud like, the membrane structure seems to float above the terrace. The semitransparent fabric offers shade on sunny days. In the night, accentuated with light, the roofing transforms into the new stage of Bregenz’s nightlife.

Clear lines and edges are provided by round steel profiles. The mesh fabric is redirected over them and fixed at the backside of the upper roof border.
The upper side of the roof is closed with a circumferential PVC stripe of about one meters width which drains to the inside on a flat roof and can be removed for inspection purposes.

As the roof has 14 supports some of the welded seams could only be closed on site. The holes for the supports are stabilized with multi-part aluminium clamps to which the funnel-shaped mosquito protection is fixed as well.
