Selectaglaze has installed secondary glazing in a 16-bed critical care ward at St Mary’s Hospital in Paddington, west London

The glazing works in conjunction with the primary windows to help provide a sterile and controllable environment. The internal pressure of individual rooms can be varied to combat the spread of infectious diseases; they also help with the eradication of dust incursion and the reduction of noise.

The company installed 62 side-hung casements with 6mm toughened glass that are fitted with special removable key handles to prevent unauthorised opening of the windows.
