What type of glass is commonly found in most sliding doors?

The glass commonly found in most sliding doors is tempered glass. Tempered glass is specially treated through a heating and cooling process that increases its strength compared to regular glass. This treatment allows it to withstand higher temperatures and provide resistance to impact, making it safer for use in situations where there is a risk of breakage.

When tempered glass does break, it shatters into small, blunt pieces rather than sharp shards, reducing the risk of injury. This safety feature is especially important in sliding doors, as they are frequently used and are more susceptible to accidents due to their interactive nature.

Other types of glass, such as plate glass, laminated safety glass, and polycarbonate, do have their own uses and benefits but do not provide the same level of strength and safety features as tempered glass. Laminated glass, for example, consists of layers that hold the glass together even when broken, but it is less common in sliding doors primarily due to cost and weight considerations.

In summary, the safety, strength, and structural integrity of tempered glass make it the preferred choice for sliding doors.
