Abstract
A glass escalator balustrade is mounted in an extruded metal channel which is secured to the escalator truss. Closed cell foam strips are disposed in contact with the balustrade panels. The strips insulate the balustrade from noises produced by the operating components of the escalator thereby rendering the escalator quieter for passengers. A layer of the sound insulating fiberglass nylon insulation is also adhered to the underside of the inner deck panels to insulate the latter from noise produced by the step rollers and step roller tracks.
