The climate in the Gulf is characterised by almost 340 days of bright sun and more or less about 200 days of high temperatures. Solar control glass has become a popular choice to counter the ill effects of very high temperatures.
The techniques used to make glass have been redeveloped over time. Today most of the buildings are using energy-efficient glass consisting of sealed double-glazing in which, typically, two sheets of 6mm glass are bonded with special highly durable sealants to a 12mm hollow aluminium space to create a 24mm thick unit. The 12mm inter-glass cavity provides a 50 per cent improvement in thermal insulation compared to clear single glass.
However, the air-space by itself, will not protect air-conditioned buildings from strong solar heating, and so a reflective coating has to be applied on the inner face of the outside pane, which furthermore can be tinted to create a reflective coloured appearance.In fact Dubai municipality is the first emirate to put legislation in place to control the minimum acceptable performance of energy-saving glass for buildings.
Without the use of solar-control glass, building facades would cause unacceptable indoor environments with excessive glare and heat, only mitigated by extensive use of blinds, curtains and huge air-conditioning bills.
