About Car Windshield Glass

Did you know that laminated auto glass used in windshields is among the 13 MOST CRITICAL COMPONENTS IN A CAR, along with air bags & steering columns? Or, that glass, when used with the right adhesive, lends 40% structural strength to the roof of your vehicle?

As you can see, there’s more to glass than meets the eye and choosing the right one is of critical importance. Two kinds of glass are used in the auto industry – laminated glass and tempered glass. Let’s try and understand what these types of glasses are and what their respective properties might be.

Laminated Glass:

Laminated glass, also known as safety glass, is a sandwich of two sheets of glass with one or more special plastic interlayer, like poly-vinyl-butyrl (PVB), in between, bonded together under heat and pressure to form a single piece. PVB is a tough, pliable material that prevents the windshield from shattering like ordinary glass, thereby protecting the occupants of the car from injury in the event of an accident or collision. In the automobile industry, the most common application of laminated glass is in designing car windshield.

The benefits of using laminated auto glass are as follows:

  • Breakage gets localized to the point of impact. As a result, visibility in other parts of the windshield is not hampered.
  • Since it has high resistance to penetration, laminated glass ensures safety for the vehicle’s passengers.
  • In case of head impact during accidents, the flexibility of laminated auto glass minimizes injuries.        
  • Laminated glass is highly effective in noise reduction and it also prevents deterioration in the appearance of interior trims by blocking UV rays.    
  • Laminated glass does not shatter on impact and can very often be repaired.

Tempered Glass:

Tempered glass is made by heating float glass to a temperature near its softening point and then forcing it to cool rapidly under controlled conditions. This particular heat treatment technique goes towards increasing the strength of annealed glass by as much as four to five times.

When compared to laminated auto glass, tempered glass shatters into pebble-like particles, increasing the possibility of injuries in case of accidents. Once broken, tempered glass cannot be repaired and the only solution is to replace it. As a result, its use in the automobile industry is restricted to rear glass and car window glass. At Windshield Experts tempered glass is used for rear glass replacement or side window replacement.

At Windshield Experts, our first attempt is always to repair the existing glass. However, depending on the damage sustained, it might be necessary to replace it as well. In doing so we only use glass that meets OEM standards, regardless of whether it is sourced from the original equipment manufacturer or other suppliers. Every precaution is taken to ensure that the glass we select fits just as perfectly as the original one. Laminated auto glass is used for windshield replacements whereas tempered glass is the preferred choice for body glasses and rear windshields.
