As those in the commercial and residential construction industry already know, tempered glass is the strongest type of glass that can be used. Basically, tempering means to heat the glass to extreme temperatures, and then rapidly put it through a high-pressure cooling process.

Let’s take a “behind the scenes” look at the five-step process used to produce tempered glass.
