Tempered glass can also be treated with chemicals and thermal treatments; these treatments help give the piece of glass more balanced internal stress capabilities.
Laminated glass is created by bonding multiple layers of glass together while under pressure and heat, with a resin called polyvinyl butyral PVB. This process creates single sheets of glass that have multiple layers. The PVB produces high sound insulation and helps keep the glass from breaking apart easily.
Before shattering, laminated glass will bend and flex. Despite not being as strong as tempered glass, laminated glass blocks around 99 percent of ultraviolet light transmission. Laminated glass is on average more expensive than tempered glass. Until recently, laminated glazings used to cost three to four times as tempered glass.

Tempered glass is used everywhere else: the side windows, the back windshields, all of those tiny panes everywhere else. The differences in these two types of glass are fundamental, and essentially very simple. Tempered glass is manufactured in a process called tempering, which used cycles of rapid heating and cooling to make the glass stronger, much-much stronger, than a traditional pane of glass.
Tempered glass, when it shatters, does not do so in jagged shards that can cut you if you look at them wrong. Instead, it disintegrates into a plethora of tiny glass balls, with little to no jagged edges to speak of. These glass BBs can be vacuumed up, and will not cause as much personal or property damage as traditional glass would in the same situation. Laminated glass, the stuff in your windshield, uses two panes of Tempered glass, with a thin inner layer of plastic or vinyl in the middle.
This plastic is called poly-vinyl butyral, or PVB. The PVB layer is not just for structural integrity, although it does add some strength to the whole windshield. Unlike normal glass, laminated glass consists of two panes of glass with an interlayer of polyvinyl butyral in between.
This thickness, along with the interlayer material, builds up the strength of the glass. There is more material for a projectile, that is, energy transference from an impact, to penetrate through.
The strong plastic interlayer possesses high tensile strength and good rigidity. All this means that it would take a lot of force to break through a windshield of laminated glass, unlike conventional single pane glass. Laminated glass also displays high resistance to shattering.
Where many standard windshields crack under normal to above normal pressure, laminated glass can remain intact.
