Tempered glass is typically how many times stronger than regular glass?

Tempered glass is typically four to five times stronger than regular (annealed) glass. The process of tempering involves heating the glass to a high temperature and then rapidly cooling it, which puts the surface into compression and increases its overall strength. This treatment not only enhances its strength but also makes it more resistant to thermal stress and impact.

The correct understanding that tempered glass can be up to four times stronger reflects its enhanced durability and safety features compared to regular glass. This is particularly important in applications such as building facades, shower doors, and automotive windows, where strength and safety are critical. Regular glass lacks this treatment, making it more prone to shattering under stress.

Noting the strength of tempered glass helps recognize its applications in various industries and why it is often selected over regular glass in safety-critical environments.
