What is the main advantage of laminated glass?

The primary benefit of laminated glass is its ability to prevent shattering when broken. This characteristic is crucial for enhancing safety in various applications. When laminated glass is impacted or subjected to stress, it does not shatter into sharp, dangerous shards; instead, it typically remains adhered to an interlayer made of PVB (polyvinyl butyral) or a similar material. This interlayer holds the glass pieces together, minimizing the risk of injury and making it an ideal choice for safety glass in windows, automobile windshields, and various other structures where strength and safety are imperative.

The other options represent benefits that are either not applicable to laminated glass or are characteristics of different materials. For instance, while some treatments can make glass more scratch-resistant, laminated glass is not specifically known for this feature. Similarly, laminated glass does not conduct heat better than regular glass and is not necessarily lighter in weight compared to other glass types.
