Types of glasses used in the windshield and its properties

Safety is one of the biggest concern for any car owner. There are many things that need to be considered when it comes to safety. One important factor is the car windshield that plays an important role. As a windshield glass is specifically designed for automobiles, it protects the driver and the passengers from any debris that could come into your vehicle and harm you. Besides, the role of the windshield glass is to provide structure to the vehicle, whether it is the front windshield glass or the rear.

How is windshield glass made?

The materials used to create a windshield glass needs to have important properties so that it can retain the shape, clarity and last for a long period of time. A good windshield also needs to be shatterproof, so that the sharp broken pieces of glass do not cause any harm or injuries to the driver and the passengers within. When it comes to fulfilling all these properties, laminated glass fits the bill right.

Laminated glass:

The lamination process begins when 2 sheets of glass are placed on different sides of a thin sheet of poly-vinyl butyral or PVB and are bonded to form one piece under heat and pressure. An autoclave heats each component as they’re pressed in between rollers. This technique fuses all the three layers together and makes the layers turn see-through.

Advantages of laminated glass that are listed below:

1)    The laminated car windshields offer UV protection

2)    Laminated glass is repairable, therefore, minor cracks or small chips can be fixed

3)    Sound reduction is excellent in laminated glass

4)    Laminated glass is highly versatility.

Tempered glass used in windshield:

Windshields, on the other hand, are also made from tempered glass by using the tempering technique. In this process, the sheet of glass is heated up to a certain temperature. Then, the glass is cooled rapidly with cold air. This process causes the glass to constantly expand and contract resulting in the outer layer hardening and the inner layer being induced with tension. This tempered glass is used for rear glass replacement or side window replacement.

When compared to laminated glass, tempered glass shatters into small pieces that can cause injuries in case of an accident.

The advantages of tempered glass are-

1)    Stronger-The tempering process makes a strong bond between the molecules in the glass

2)    Heat resistant- The process of making tempered glass involves high temperatures that make the glass more resistant to high temperature.

Once broken, tempered glass cannot be repaired and the only solution is to replace it. Although each windshield glass has different functions, but together, in an accident they protect you from flying sharp glass. In the case of a rollover, windshields retain the roof’s rigidity while the side airbags protect the passengers within.

How to choose the right windshield?

The glass used should be of OEM standards, even if it is sourced from the original equipment manufacturer or suppliers. Every precaution must be taken to ensure that the glass fits just as perfectly as the original one. Laminated glass is mostly used for windshield replacement and tempered glass is preferred for body glasses and rear windshields.

In case you have any doubts related to laminated auto glass, tempered glass, windshield replacements or body glass replacements, make sure to get in touch with the right experts.
