Laminated glass is a type of safety glass that holds together when shattered. It is made of two or more sheets of glass, with a thin layer of plastic (polyvinyl butyral) sandwiched between them.
When laminated glass is shattered, the plastic layer holds the glass together. This prevents the glass from breaking into large, sharp pieces that could cause injuries.
Laminated glass was invented in 1903 by French chemist and inventor Édouard Benedictus. He discovered that if two pieces of glass are laminated with a thin layer of plastic, they will hold together when shattered.
Laminated glass is most commonly used in windows and doors. It is classed as a type of safety glass and can be used in any location where safety is a concern, such as schools, hospitals, and airports. Laminated glass is also used in cars and motorcycle helmets.
Laminated glass is often more expensive than non laminated glass, but can be worth the extra cost due to its increased durability and safety benefits.
Laminated glass can be cut, but it is more difficult than traditional float glass. It also requires special tools and safety equipment.
Laminated glass is shatterproof and Toughened Glass is not, so laminated glass would be a better choice for safety reasons. However, toughened glass is stronger than laminated glass and can withstand more impact. Both are considered safety glass and meet Australian AS1288 standards.
You can tell laminated glass from other types of glass by viewing it’s edges. If you hold the glass up to a light source and then view it at ninety degrees you will see that laminated has a distinct interlayer while regular float glass does not. Additionally, laminated glass sounds different than normal float glass when knocked on.
