Tempered glass is manufactured through a process of extreme heating and rapid cooling that enhances its strength compared to regular glass. This thermal treatment alters the internal structure, allowing tempered glass to handle greater stress and impact. The most significant feature of tempered glass is that it is approximately four to five times stronger than standard glass of the same thickness, which makes it an ideal material for various applications requiring higher safety and durability standards.

The assertion that tempered glass is four times stronger highlights its increased durability, providing valuable benefits in environments where glass is subjected to high stress, such as in windows, doors, and facades. This strength is crucial in preventing breakage and ensuring safety, particularly in construction and automotive applications. Overall, the enhanced strength and safety features of tempered glass make it a preferred choice in many situations where normal glass would not be sufficient.
