Which type of glass is known for being impact-resistant and safe?

Tempered glass is a type of glass known for its impact resistance and safety features. The process of tempering involves heating the glass to high temperatures and then rapidly cooling it, which increases its strength compared to standard (annealed) glass. This process allows tempered glass to withstand greater forces without breaking, making it ideal for applications where safety and durability are critical, such as in doors, shower enclosures, and vehicle windows.

When shattered, tempered glass breaks into small, blunt pieces rather than sharp shards, reducing the risk of injury. This characteristic is particularly important in environments where human safety is a priority. In contrast, other types of glass may not have the same level of strength or safety. For example, annealed glass is more susceptible to breaking and can pose a greater safety hazard upon shattering. Insulated glass is designed for energy efficiency but does not specifically enhance impact resistance. Float glass, while commonly used in windows, lacks the strength and safety benefits provided by tempering.
