Essential Guide to Auto Glass: Types and Repair Tips

If your vehicle crashes into a roadside object and the windshield shatters, do you know what happens next? Unlike ordinary glass, which fragments into dangerous shards, automotive windshields break into small, non-threatening pieces.

This is because automotive glass is specially engineered to withstand impacts and protect passengers.

What are the primary types of auto glass?

Auto glass mainly falls into two categories: laminated and tempered glass.

Windshields consist of laminated safety glass, whereas side windows and rear windows are made from tempered glass.

Laminated Glass: Developed in the 1920s, laminated safety glass involves bonding two layers of glass with Polyvinyl Butyral, then heating to create a strong, durable barrier.

Because of its design, laminated glass stays intact upon impact, preventing dangerous shards from flying off. It also acts as a cushion, reducing injury if you hit your head on the windshield.

Tempered Glass: Tempered glass is made by heating a single glass sheet to extreme temperatures and then rapidly cooling it.

This type of glass is optimal for side windows, as it shatters into small, harmless pieces when impacted.

Unlike laminated glass, tempered glass must be replaced if damaged, as repairs are not feasible.

How to Replace Your Vehicle’s Windshield

Contact a professional auto glass technician for windshield replacement. They will remove wipers, moldings, and the cowl, then clean the old adhesive and apply a new layer. The new windshield is then carefully installed. Costs are usually covered by insurance or paid out-of-pocket.

Driving with a cracked or damaged windshield is risky. A intact windshield is vital to your safety, acting as a barrier during collisions and helping prevent ejection from the vehicle.
