What is the Difference between Laminated and Tempered Auto Glass?

Laminated glass and tempered glass are two of the most important and crucial types of glass for your automobile. But what is the difference between these two life-saving types of glass?

Laminated glass is made up of two plate glass sheets, which are stacked on top of each other, with an inner layer made of plastic called polyvinyl butryal, or PVB. When broken, laminated glass stays in one piece, so it is perfect for your windshield because it prevents shards of glass hitting the driver and passengers in accidents. This is why you see the spider web effect in broken windshields. This is because the glass breaks without actually shattering.

Tempered glass is used elsewhere on the car, including the back windshield and side window glass. Tempered glass is made by heating and cooling a sheet of glass in a tempering furnace. This process is referred to as “air quenching”, which makes the glass four to five times stronger than a standard sheet of glass. Tempered glass doesn’t have to be quite as strong as laminated glass because the windshield is key for the structural integrity of the car. Tempered glass will still, however, break into small shards that are not as painful as typical broken glass.
