Which type of glass is known for being three to five times stronger than regular glass?

Tempered glass is recognized for its enhanced strength compared to regular glass. The manufacturing process involves heating the glass to a high temperature and then rapidly cooling it. This process not only increases the glass's strength, making it three to five times stronger than standard glass, but also makes it more resistant to thermal stress and impact.

When tempered glass is broken, it shatters into small, blunt pieces instead of sharp shards, which reduces the risk of injury. This characteristic makes it a preferred choice for safety applications in various settings, such as in buildings, vehicles, and shower doors. Its increased durability and safety features are key reasons why tempered glass is commonly used in situations where the risk of breakage is high.

The other types of glass listed do not possess the same level of strength as tempered glass. Reflective glass generally serves aesthetic and energy efficiency purposes rather than strength, coated glass typically involves a surface treatment and does not enhance the base material's strength significantly, and wired glass integrates a wire mesh for safety but lacks the strength-to-weight ratio that tempered glass offers.
