subject: The History Of Tempered Glass [print this page] People often ask why laminated glass isn't used for every window in an automobile. There are two reasons. First, laminated glass is much more expensive to manufacture, and would add substantially to the cost of the vehicle if it were used for every window. The second reason is that it is very difficult to break through a piece of laminated glass. In the event of an emergency, rescue crews need to be able to pull people out of the vehicle as quickly as possible, and tempered glass is much easier to break than laminated glass.
