Glass was first discovered around 5,000 BC. For centuries, individual craftmanship dominated and it was not until the 20th Century that glass production became industrialized and mass produced in sheets. But there was still one major drawback: glass had to be ground and polished on both sides to obtain the desired quality – a process that was very time-consuming and costly. 

Then came perhaps the greatest innovation in glass history – the introduction of the Float Glass production process, popularized in the 1960s. This breakthrough led to a dramatic rise in the use of glass around the world.  

Float glass is the foundation of Guardian’s offerings today, from coated solar control glass, to laminated safety, anti-reflective and mirror glass.
