The Diamond Series glass roof revolving doors from Record Doors were installed for the main entrance at 388 George Street in the heart of Sydney CBD.
Located on the corner of King Street, the building, originally constructed in 1976, is a 28-storey A-Grade commercial office tower that has already seen two extensive lobby refurbishments over its 44-year history. The first was in 1998 when Record’s former Australian business, AGP Door Systems, installed its first generation glass roof revolving doors from the Crystal Series. The second was completed by Multiplex this year when architects FJMT included Record’s second generation glass roof revolving door, Diamond Series, for the main entrance.
The Diamond Series revolving doors on this project are truly two of a kind, pushing the limits of frameless glass design in a revolving door. FJMT sought frameless glass revolving doors that could also assist with supporting the dead load weight of the surrounding frameless glass design.
To achieve this, Record Automatic Doors worked with the façade contractor Permasteelisa to take their standard Diamond Series design and make it bigger and bolder to fit the new requirements.
Permasteelisa installed the curved glass sidewalls and roof panels in triple laminated low iron laminated glass with SGP interlayers and a structural recessed floor track. The rest of the door design, from the frameless glass centre carousel to floor pit mounted drive motors was as per the standard Diamond design. The door was clad in Rimex Quartz Champagne stainless steel.
