Curtain Wall Glazing

The traditional curtain wall is a frame of aluminium with mullions and transoms quite similar to large framed glazing excepts that the walls form an independent envelope around the main structure and are generally not resting on the concrete structure but only connected to it. The design factors of wind loading and provisions for expansions and movements of wall v/s the structure and glass v/s the aluminium are to be considered carefully. Planimetry of the whole glass wall as a single unit and special sealing elements, material and techniques make it a highly specialized job. The glass is kept in place by placing it in the sash and fixing with a pressure plate & screws.
