The private gym facility in the heart of Canary Wharf is a training facility for the staff of HSBC banking Group. The glass is automatically controlled with motion and light sensors. This instantly switches them from clear the frosted state. When the space is unoccupied the glass switches to the opaque condition. This preserves electricity and longevity of the glass. The glass in this application is fitted an acoustic internal laminate to prevent noise transfer in and out of the space.
