Dubai blaze raises questions on skyscraper design

Dubai

A BLAZE that engulfed a Dubai skyscraper on New Year's Eve - the emirate's third high-rise fire in three years - has raised fresh questions about the safety of materials used on the exteriors of tall buildings across the wealthy region.

Hundreds of gleaming towers rose up in Gulf Arab states, especially the United Arab Emirates and Qatar, during the past decade's economic boom. Ultra-modern, flamboyant designs often involved heavy use of cladding - layers fixed to the outside of buildings for decoration, insulation or protection.
