Why do we use laminated glass in the walls of glass elevator cabs?

Laminated glass is preferred for use in the walls of glass elevator cabs primarily because, if the glass cracks, the plastic interlayer holds the fragments in place. This is a critical safety feature, as it minimizes the risk of injury from falling shards of glass. The interlayer helps to keep the glass pieces adhered to each other, creating a barrier that maintains the integrity of the elevator cab and protects passengers inside even if the glass is damaged.

This safety characteristic is particularly important in the context of elevators, where the environment requires high standards for passenger safety and structural integrity. Additionally, laminated glass also has other advantages, such as reducing noise and offering UV protection, but its function in providing safety through the retention of fragments when cracked is the most crucial reason for its use in elevator applications.
