Implementation ETFE cushions

These roof lights are made from a transparent foil with print. Roof light cushions consist of three layers of foil: an outer layer of 200 my, a middle layer of 150 my and an inner layer of 150 my. The print is on the inner face of the outer layer of ETFE foil .

Inflation system

The inflation system used in the "Hartley Library Learning Centre" consists of two units. Each unit is capable of maintaining the pressure in two cushions, even when 10% of the cushions are damaged. Each unit has an automatic control system installed with one operational fan and one stand-by. Pressure failure in the cushions will trigger an alarm in the monitoring system of the building.
