The final cladding panel for the for the Burj Dubai – the world’s tallest building – has been completed.

The 6m-long glass, aluminium and steel panel will be installed at the bottom of Burj Dubai’s spire, to fit with the other 24,348 panels.

The materials used for the 24,348 cladding panels include reflective glazing, aluminium mullions and textured steel spandrels with vertical stainless steel tubular fins to accentuate the world’s tallest tower height.

Double-glazed and factory-sealed panels of more than 18 different strength specifications and over 200 sizes have been used in the project.

The Arabian Aluminium Company began work on external cladding in April 2007. The 818m Burj tower has been developed by Emaar as part of the AED73.4bn ($19.98bn) Downtown Burj Dubai scheme.

The Burj Dubai will open in December instead of September this year, as was originally planned, according to local press reports.
