Tempered glass is fundamentally different from laminated glass due to the specific processes each undergoes for their respective properties. Tempered glass is produced through a heat treatment process, which involves heating the glass to a high temperature and then cooling it rapidly. This thermal treatment significantly increases the glass's strength and makes it highly resistant to thermal stress and impact. In comparison, laminated glass is made by sandwiching a polyvinyl butyral (PVB) or other interlayer between two or more layers of glass. This interlayer provides additional safety by ensuring that if the glass breaks, the shards adhere to the interlayer rather than scattering, reducing the risk of injury.

The distinction in their applications is crucial. For instance, tempered glass is often used in applications where strength and thermal resistance are required, such as in shower doors, glass doors, and facades. Laminated glass, with its safety features, is commonly used in environments where safety is a priority, such as in car windshields and overhead glazing. This understanding highlights the different benefits they provide based on their manufacturing processes and end uses.
