Tempered Glass vs. Laminated Glass

Wondering what type of glass window is best for your vehicle? Here’s what you need to know about tempered and laminated glass.

Tempered Glass

Tempered glass, also known as toughened glass, is created by heating and rapidly cooling a pre-cut standard piece of glass in a tempering furnace. The pre-cut and edged piece of glass is heated up to around 1200°F. After being heated up; the glass is then cooled rapidly. This process is known as quenching.

Quenching produces a hardened piece of glass that is four to five times stronger than before the tempering process. The final product tempered glass is harder to break. Tempered glass is most commonly used for passengers windows on cars while laminated glass makes up your front and rear windshield most of the time. When tempered glass breaks, it is designed to shatter into small pieces that are less likely to cause added injury or damage.

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

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.

Cost

Laminated glass is on average more expensive than tempered glass. Until recently, laminated glazings used to cost three to four times as tempered glass. Car manufacturers are required to use laminated glass for windshields. More and more companies are starting to use laminated glass for side and rear windows.

Laminated Tempered Glass

The combination of laminated and tempered glass is certainly possible but very difficult. When manufacturing laminated tempered glass, the thickness of PBV used has to be just right, or the glass is useless. If manufactured successfully, laminated tempered glass can have many useful applications. A number of car manufacturers are using this technology in their windows now.
