Esch-sur-Alzette (LUX) 2022

The two-layer air dome is a portable hiking hut. The pneumatic envelope is mounted on a trailer with two folding wings. The shelter is designed to be set up and dismantled (inflated and deflated) several times at various locations along the Minnet Trail to offer hikers accommodation.

The pneumatic/inflatable envelope is a hemispherical shape formed by a double membrane system. Both layers are made of highly translucent PVC-PES fabric. 10 transparent windows are integrated into the envelope to provide views of the exterior.

Synthetic cords are used to connect the outer and inner layers at specific points. Zip fasteners and aluminium clamping strips, positioned all the way round the base of the dome, connect it to the trailer platform and ensure a rapid assembling and dismantling process.

1000 Pa pressure is provided by a central inflation system.
