Under uniform loading, how much stronger is tempered glass compared to annealed glass of the same size and thickness?

Tempered glass is designed to be significantly stronger than annealed glass due to the tempering process, which involves heating the glass to high temperatures and then rapidly cooling it. This process induces compressive stresses on the surface of the glass, making it much more resilient against impact and thermal stress.

Specifically, tempered glass can be up to four times stronger than annealed glass of the same size and thickness when subjected to uniform loading. This enhanced strength makes tempered glass an ideal choice for applications where safety and durability are paramount, such as in building facades, shower doors, and glass doors.

With this understanding, the choice indicating that tempered glass is four times greater in strength than its annealed counterpart accurately reflects the industry standards and technical specifications regarding glass performance under stress.
