What is double tempered glass and what are the benefits? 

Tempered glass is used when strength and safety are the priorities. The main difference between tempered glass and standard glass is all in the way it is made. The tempering process involves heating the glass to approximately 600 C (1100◦ Fahrenheit) then very quickly quenching it in cold air to reinforce the glass with strength. 

Tempered glass is nearly four times stronger than regular glass, which significantly reduces the likelihood of it breaking on impact and means that it is much less likely to scratch. It also has a greater degree of shock protection. 

This rapid heat and cool process changes the structure of the glass to make it more impact resistant and if broken, it breaks differently. When standard glass is broken it will splinter into jagged, irregular size shards, whereas tempered glass, often referred to as ‘safety glass’, will shatter into smaller granular pieces which are much less likely to cause any injury.  Double tempering repeats this process in order to further reinforce the glass with strength.

Due to its safety, strength and perfect clarity, double tempered glass is chosen for a wide range of uses such as aquariums, architecture and car windscreens. We also use it for our screen protector for the exact same reasons.
