Solar Gard introduced the platinum window film using technology 'multi-layered sputtering', which is the continued development of sputtering. Multi-layered sputtering is shooting of micro particles with various layers of metal.

"So, each sheet of the platinum window film is composed of many layers of metal. Among them, titanium, indium, gold and silver to reject the heat energy," said Troy Kurniawan, Solar Gard Brand Manager of Indonesia at event media gathering in Jakarta, Indonesia, Friday (March 30, 2012).

"The technology used in Solar Gard is better than the nanotechnology. Nano has a disadvantage compared to the kind of sputtering, in which Nano tend to absorb heat," added Troy.
