Laminated Glass prevents injury!

Each time a glass cup or a plate is broken into pieces I take care that these do not injure the person handling them to dispose off. Still I see persons getting glass piece pricks into their feet as they walk on the rural roads. Nowadays there is also a change: I see smaller, regular and similar glass pieces (that resemble large sugarcane crystals) lying on the road when there is an accident, or on the fight scene in movie pictures! These pieces come out of Laminated Safety Glass (also called Automotive Glass). This special glass is a toughened and high strength glass. When shattered it holds together its broken pieces. It also prevents itself from breaking down into large sharp pieces even when it falls down from a height. Inside this glass there is an interlayer of Polyvinyl butyral (PVP). When it is broken the two outer layers of (broken) glass sheets are kept bonded only by this inner layer!

It is a wonder glass that doesn’t injure any one even when it is broken – unlike our heart!

Laminated glass is normally used when there is a possibility of human impact or where the glass could fall if shattered. Skylight glazing and automobile windshields typically use laminated glass.
