Building Skin Fabric

The membrane is constructed from 2 skins of PTFE coated fibreglass separated by an air gap of approximately 500mm and pre-tensioned over a series of trussed arches. These arches span up to 50 metres between the outer bedroom wings of the hotel which frame the atrium, and are aligned with the vertical geometry of the building. The double-curved membrane panels so formed are able to take positive wind pressures by spanning from truss to truss and negative wind pressures by spanning sideways. Additional cables have been provided running on the surface of the fabric to reduce the deflection of the membrane.
