PROJECT DESCRIPTION
This project consists in the refurbishment of Rennes bus station, incorporating a new canopy which shelters 16 bus departure bays and protects travellers from inclement weather.
This new canopy is composed of a total of 59 two-layer ETFE cushions distributed in a single continuous line, 176 m long. In the first part, the cushions, of variable length, follow the shape of the adjacent building. In the last part, the cushions, of constant length, follow a single alignment.
This configuration covers a total space of 754 m².
BASE TÉCNICA
TECHNICAL BASE
This installation has been carried out using IASO’s standardised AVIS TECHNIQUE system for ETFE cushions.
The ETFE cushions have 2 layers. The upper layer is printed with a design of aluminium-coloured dots with a diameter of 74 mm, as prescribed by the architect AREP. The thicknesses of the ETFE membranes are 200, 250 and 300 microns.
The perimeter of the roof is bordered by aluminium flashings and a sealing membrane integrated into the roof profiles to keep the roof watertight.
The 3 expansion joints of the structure have been treated with white PVC membrane.
